Update release.yml

- Modular builders for `gcc`, `clang`, `msvc`
- Platform-specific binary path generation (Linux/macOS/Windows)

Changed:
- Build configuration moved to `[build]` (`language`, `standard`, `compiler`)
- `dcr.toml` formatting now includes the `[build]` section
- Build uses built-in `debug/release` flags per compiler
- Build compiles all `*.c/*.cpp` files in `src/` into a single binary (no incremental build)
- Updated `dcr.toml` examples in documentation

+# FAQ
+
+## What is this project about?
+`dcr` is a tool for managing C/C++ projects and their dependencies.
+It is inspired by Cargo, but it is not a direct equivalent of Makefile, CMake, or other classic build systems.
+
+The goal is to provide a simpler and easier-to-configure development workflow.
+
+## How is the project developed?
+The project is written in Rust and is primarily developed by one maintainer, Dexoron.
+
+AI tools are used during development, but they do not write the project end-to-end. Their role is limited to supporting specific tasks (for example, suggestions, wording checks, and translations).
+
+## Which tools are used for development?
+Main development stack:
+- `RustRover` 2025 - development IDE.
+- `Codex` (`GPT-5.3-Codex (medium)`) - primary AI tool, integrated via JetBrains AI Chat.
+- `Rust` - main project language.
+- `Cargo` - tool for building, testing, and dependency management in Rust projects.
+
+## Is the project open source?
+Yes, the project is open source.
+You can propose ideas, report issues, and contribute code changes.
+
+The project is distributed under the MIT license (see `LICENSE`).
+
+## How can I contribute?
+Thank you for contributing.
+You can:
+- help with code;
+- help with translations;
+- help with documentation;
+- suggest an idea or report a bug.
+
+### If you want to submit changes (code, translation, documentation)
+1. Fork the required repository: `dexoron/dcr` (main project) or `dexoron/dcr-site` (project website).
+2. Make your changes following the rules in `CONTRIBUTING.md`.
+3. Push changes to your fork.
+4. Open a Pull Request.
+5. Wait for review.
+
+### If you want to report a problem or suggest an idea
+1. Open the relevant repository: `dexoron/dcr` or `dexoron/dcr-site`.
+2. Go to the `Issues` tab.
+3. Create an Issue and specify its type (bug, suggestion, question/help).
+4. Describe the problem or idea clearly and concisely.
+5. Wait for feedback.
+
+## How do I install `dcr`?
+Available installation methods may vary by project version.
+Recommended path:
+- check instructions in `README.md`;
+- if there is no prebuilt package for your platform, build from source using `cargo build --release`.
+
+## How can I get started quickly?
+Minimal workflow:
+1. Install `dcr`.
+2. Create a project (or open an existing C/C++ project).
+3. Initialize `dcr` configuration.
+4. Add project dependencies.
+5. Build using `dcr`.
+
+For detailed commands and examples, see `README.md` and the project documentation.
+
+## What is the project status?
+`dcr` is under active development.
+This means some interfaces and behaviors may change between versions.
+
+Before upgrading, check the changelog and release notes.
+
+## Which systems does `dcr` support?
+`dcr` targets modern C/C++ development environments.
+Actual compatibility depends on the `dcr` version, operating system, and toolchain.
+
+Before starting, check documentation for:
+- supported operating systems;
+- supported compilers and linkers;
+- version-specific limitations.
+
+## How is `dcr` different from Make/CMake?
+`dcr` does not aim to be a direct replacement for Make/CMake.
+Its main focus is simplifying project and dependency management with a Cargo-like experience.
+
+If you need low-level, full control over build steps, classic tools may be a better fit.
+If you want a simpler and more uniform configuration model, `dcr` may be more convenient.
+
+## Where can I find documentation and examples?
+Primary sources:
+- `README.md` in the repository;
+- project documentation (see the project website);
+- `Issues` for known problems and discussions.
+
+## How do I report a bug properly?
+To make a bug report easy to reproduce, include:
+1. `dcr` version.
+2. OS and compiler/toolchain version.
+3. Steps to reproduce.
+4. Expected behavior.
+5. Actual behavior and error output.
+6. Minimal project example (if possible).
+
+Submit bugs and issues through `Issues` in the relevant repository.

 # DCR (Dexoron Cargo Realization)
 
-DCR — это утилита для управления проектами на C. Она задает единый формат проекта, дает команды для создания, сборки и запуска, и использует один конфигурационный файл `dcr.toml`.
+DCR is a utility for managing C/C++ projects in a Cargo-like style.
 
-Проект находится на стадии MVP. Текущая реализация написана на Python и в будущем будет переписана.
+The current implementation is written in Rust.
 
-## Зачем DCR
+## Why DCR
-- Единая структура проекта без ручной настройки
+- Unified project structure without manual setup
-- Простые команды для типовых задач
+- Simple commands for common tasks
-- Прозрачная компиляция и предсказуемые профили сборки
+- Transparent compilation and predictable build profiles
 
-## Возможности
+## Features
-- Создание нового проекта или инициализация текущей директории
+- Create a new project or initialize the current directory
-- Сборка проекта в профилях `debug` и `release`
+- Build a project with `debug` and `release` profiles
-- Запуск собранного бинарника
+- Run the compiled binary
-- Очистка результатов сборки
+- Clean build artifacts
-- Генерация минимального шаблона C-проекта
+- Generate a minimal C project template
+- Update the binary via `dcr --update` (GitHub Releases, not for pacman/AUR installs)
 
-## Быстрый старт
+## Supported Platforms
-Создать новый проект:
+- Linux: `x86_64-unknown-linux-gnu`
+- macOS Intel: `x86_64-apple-darwin`
+- macOS Apple Silicon: `aarch64-apple-darwin`
+- Windows: `x86_64-pc-windows-msvc`
+
+## Installation

+
+## Update
+
+- If DCR was installed from GitHub release assets, `install.sh`, `install.ps1`, or built manually:
+  - use `dcr --update`
+- If DCR is installed via `pacman/AUR`:
+  - update with your package manager: `paru/yay -Syu dcr` or `sudo pacman -Syu dcr`
+  - `dcr --update` detects package-managed installs and asks you to update via package manager
+
+## Quick Start
+
+Create a new project:
 `dcr new hello`
 
-Или инициализировать текущую директорию (директория должна быть пустой):
+Or initialize the current directory (the directory must be empty):
 `dcr init`
 
-Структура проекта:
+Project structure:
-```
+
+```txt
 hello/
 - src/
 - - main.c
 - dcr.toml
 ```
 
-## Команды
+Build and run the project:
+`dcr run` or `dcr run --release`
+
+## Commands
 
 ### `dcr new <name>`
-Создает проект в текущей директории с указанным именем.
+Creates a project with the specified name in the current directory.
 
 ### `dcr init`
-Создает проект в текущей директории. Имя проекта будет равно имени директории. Директория должна быть пустой.
+Creates a project in the current directory. The project name is taken from the directory name. The directory must be empty.
 
 ### `dcr build [profile]`
-Собирает проект. Если профиль не указан, используется `--debug`.
+Builds the project. If no profile is specified, `--debug` is used.
 
 ### `dcr run [profile]`
-Собирает проект и запускает бинарник. Если профиль не указан, используется `--debug`.
+Builds the project and runs the binary. If no profile is specified, `--debug` is used.
 
-Запуск вручную:
+Run manually:
-`./target/<profile>/main`
+`./target/<profile>/<name>`
 
 ### `dcr clean`
-Удаляет папку `target` в корне проекта.
+Removes the `target` directory in the project root.
 
-## Профили сборки
+## Build Profiles
-Поддерживаются два профиля:
+Two profiles are supported:
-- `--debug` (по умолчанию) — флаги: `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDEBUG`
+- `--debug` (default) - flags: `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDEBUG`(Clang)
-- `--release` — флаги: `-O3 -DNDEBUG -march=native`
+- `--release` - flags: `-O3 -DNDEBUG -march=native`(Clang)
 
-## Конфигурация
+## Configuration
-Основной файл проекта — `dcr.toml`. Сейчас он создается автоматически и служит точкой входа для будущих настроек.
+The main project file is `dcr.toml`.
 
-Пример `dcr.toml`:
+Example `dcr.toml`:
-```
+
+```toml
 [package]
 name = "hello"
 version = "0.1.0"
+
+[build]
 language = "c"
+standard = "c11"
 compiler = "clang"
 
 [dependencies]
 ```
 
-## Установка в PATH
+## Requirements
-Чтобы вызывать `dcr` из любой директории, можно сделать symlink в `~/.local/bin`:
+- Rust toolchain (`rustc`, `cargo`) - for building DCR from source
-```sh
+- C compiler (`clang`, `gcc`, or 'cl'(msvc))
-ln -s "$PWD/dcr" ~/.local/bin/dcr
-```
-Убедитесь, что `~/.local/bin` находится в `PATH`.
 
-## Пример проекта
+## Releases
-`src/main.c` содержит минимальный `Hello, World!`:
+Releases are built automatically via GitHub Actions (`.github/workflows/release.yml`) when a tag matching `v*` is pushed.
-```c
-#include <stdio.h>
 
-int main(void) {
+## License
-    puts("Hello, World!");
+See `LICENSE`.
-    return 0;
-}
-```
-
-## Требования
-- C-компилятор (например, `gcc` или `clang`)
-- Python 3.14.2 (для текущей версии DCR)
-- uv (менеджер проекта для Python)
-
-## Статус и планы
-Проект в стадии MVP. Планируется переписывание на более подходящий язык и расширение функциональности:
-- более гибкая конфигурация через `dcr.toml`
-- расширяемые профили сборки
-- менеджер пакетов
-
-## Лицензия
-См. файл `LICENSE`.

+# FAQ
+
+## В чем суть проекта?
+`dcr` - это инструмент для управления C/C++ проектами и их зависимостями.
+Он вдохновлен Cargo, но не является аналогом Makefile, CMake или других классических систем сборки.
+
+Цель проекта - дать более простую и удобную в настройке среду для разработки.
+
+## Как разрабатывается проект?
+Проект написан на Rust и в основном развивается одним разработчиком - Dexoron.
+
+В работе используются ИИ-инструменты, но они не пишут проект целиком: их роль - помощь с отдельными задачами (например, советы, проверка формулировок, переводы и т.д.).
+
+## Какие инструменты используются для разработки?
+Основной стек разработки:
+- `RustRover` 2025 - IDE для разработки.
+- `Codex` (`GPT-5.3-Codex (medium)`) - основной ИИ-инструмент, интегрированный через JetBrains AI Chat.
+- `Rust` - основной язык проекта.
+- `Cargo` - инструмент сборки, тестов и управления зависимостями Rust-проектов.
+
+## Проект открытый?
+Да, проект открыт (Open Source).
+Вы можете предлагать идеи, находить ошибки и вносить изменения в код.
+
+Проект распространяется по лицензии MIT (см. `LICENSE`).
+
+## Как внести вклад?
+Спасибо за желание помочь проекту.
+Вы можете:
+- помочь с кодом;
+- помочь с переводом;
+- помочь с документацией;
+- предложить идею или сообщить о баге.
+
+### Если вы хотите внести изменения (код, перевод, документация)
+1. Сделайте форк нужного репозитория: `dexoron/dcr` (основной проект) или `dexoron/dcr-site` (сайт проекта).
+2. Внесите изменения с учетом правил из `CONTRIBUTING.md`.
+3. Отправьте изменения в свой форк.
+4. Создайте Pull Request.
+5. Дождитесь ревью.
+
+### Если вы хотите сообщить о проблеме или предложить идею
+1. Откройте нужный репозиторий: `dexoron/dcr` или `dexoron/dcr-site`.
+2. Перейдите во вкладку `Issues`.
+3. Создайте Issue и укажите тип (баг, предложение, вопрос/помощь).
+4. Опишите проблему или идею кратко и понятно.
+5. Дождитесь обратной связи.
+
+## Как установить `dcr`?
+Актуальные способы установки зависят от текущей версии проекта.
+Рекомендуемый путь:
+- проверьте инструкции в `README.md`;
+- если готового пакета для вашей платформы нет, соберите проект из исходников через `cargo build --release`.
+
+## Как быстро начать работу?
+Минимальный сценарий:
+1. Установите `dcr`.
+2. Создайте проект (или перейдите в существующий C/C++ проект).
+3. Инициализируйте конфигурацию `dcr`.
+4. Добавьте зависимости проекта.
+5. Запустите сборку через `dcr`.
+
+Подробные команды и примеры смотрите в `README.md` и документации проекта.
+
+## На какой стадии проект?
+`dcr` активно развивается.
+Это означает, что интерфейсы и поведение некоторых функций могут меняться между версиями.
+
+Перед обновлением рекомендуется читать changelog и проверять заметки к релизу.
+
+## С какими системами работает `dcr`?
+`dcr` ориентирован на современные среды разработки C/C++.
+Фактическая совместимость зависит от версии `dcr`, операционной системы и используемого toolchain.
+
+Перед началом работы проверьте в документации:
+- поддерживаемые ОС;
+- поддерживаемые компиляторы и линкеры;
+- ограничения конкретной версии.
+
+## Чем `dcr` отличается от Make/CMake?
+`dcr` не пытается быть прямой заменой Make/CMake.
+Главный фокус `dcr` - упростить управление проектом и зависимостями в стиле, близком к опыту Cargo.
+
+Если вам нужен низкоуровневый полный контроль над процессом сборки, классические инструменты могут быть привычнее.
+Если нужна более простая и единообразная модель конфигурации - `dcr` может быть удобнее.
+
+## Где смотреть документацию и примеры?
+Основные источники:
+- `README.md` в репозитории;
+- документация проекта (смотреть сайт проекта);
+- `Issues` для известных проблем и обсуждений;
+
+## Как правильно сообщить о баге?
+Чтобы баг-репорт можно было быстро воспроизвести, укажите:
+1. Версию `dcr`.
+2. ОС и версию компилятора/toolchain.
+3. Шаги воспроизведения.
+4. Ожидаемое поведение.
+5. Фактическое поведение и текст ошибки.
+6. Минимальный пример проекта (по возможности).
+
+Баги и проблемы отправляйте через `Issues` в соответствующем репозитории.

+# DCR (Dexoron Cargo Realization)
+
+DCR — это утилита для управления проектами на C/C++ в стиле Cargo.
+
+Текущая реализация написана на Rust.
+
+## Зачем DCR
+- Единая структура проекта без ручной настройки
+- Простые команды для типовых задач
+- Прозрачная компиляция и предсказуемые профили сборки
+
+## Возможности
+- Создание нового проекта или инициализация текущей директории
+- Сборка проекта в профилях `debug` и `release`
+- Запуск собранного бинарника
+- Очистка результатов сборки
+- Генерация минимального шаблона C-проекта
+- Обновление бинарника через `dcr --update` (GitHub Releases, не для pacman-установок)
+
+## Поддерживаемые платформы
+- Linux: `x86_64-unknown-linux-gnu`
+- macOS Intel: `x86_64-apple-darwin`
+- macOS Apple Silicon: `aarch64-apple-darwin`
+- Windows: `x86_64-pc-windows-msvc`
+
+## Установка
+
+### Пакетный менеджер
+
+**ArchLinux**
+```sh
+yay -S dcr # или paru и остальные менеджеры пакетов AUR 
+```
+
+### Из исходников
+
+```sh
+git clone https://github.com/dexoron/dcr.git
+cd dcr
+cargo build --release
+mkdir -p ~/.local/bin
+ln -sf "$PWD/target/release/dcr" ~/.local/bin/dcr
+```
+
+### Через install.sh (Linux/macOS)
+
+```sh
+curl -fsSL https://dcr.dexoron.su/install.sh | bash
+```
+
+### Через install.ps1 (Windows)
+
+```powershell
+irm https://dcr.dexoron.su/install.ps1 | iex
+```
+
+Оба скрипта при запуске спрашивают:
+- скачать готовый бинарник из GitHub Release
+- или собрать проект из `git`
+
+Релизные ассеты:
+- `dcr-x86_64-unknown-linux-gnu`
+- `dcr-x86_64-apple-darwin`
+- `dcr-aarch64-apple-darwin`
+- `dcr-x86_64-pc-windows-msvc.exe`
+
+## Обновление
+
+- Если DCR установлен из GitHub Releases, через `install.sh`, `install.ps1` или собран вручную:
+  - используйте `dcr --update`
+- Если DCR установлен через `pacman/AUR`:
+  - обновляйте через пакетный менеджер: `paru/yay -Syu dcr` или `sudo pacman -Syu dcr`
+  - `dcr --update` определяет пакетную установку и подсказывает обновляться через пакетный менеджер
+
+## Быстрый старт
+
+Создать новый проект:
+`dcr new hello`
+
+Или инициализировать текущую директорию (директория должна быть пустой):
+`dcr init`
+
+Структура проекта:
+
+```txt
+hello/
+- src/
+- - main.c
+- dcr.toml
+```
+
+Сборка и запуск проекта:
+`dcr run` или `dcr run --release`
+

+
+## Профили сборки
+Поддерживаются два профиля:
+- `--debug` (по умолчанию) — флаги: `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDEBUG`(Clang)

+language = "c"
+standard = "c11"
+compiler = "clang"
+
+[dependencies]
+```
+
+## Требования
+- Rust toolchain (`rustc`, `cargo`) - Для ручной сборки DCR
+- C-компилятор (`clang`, `gcc` или 'cl'(msvc))
+

+# AUR publishing
+
+This repository includes an automated AUR publish workflow:
+- package files: `packaging/aur/dcr/PKGBUILD`, `packaging/aur/dcr/.SRCINFO`
+- workflow: `.github/workflows/aur.yml`
+
+## One-time setup
+
+1. Create the `dcr` package on AUR and initialize its git repository.
+2. Create an SSH key pair for CI.
+3. Add the public key to your AUR account.
+4. Add the private key to GitHub Actions secret `AUR_SSH_PRIVATE_KEY`.
+
+## Release flow
+
+1. Bump project version in `Cargo.toml`.
+2. Push tag `v<version>` (example: `v0.2.2`).
+3. GitHub Actions will:
+- compute source tarball SHA256
+- render `PKGBUILD` and `.SRCINFO`
+- push updates to `ssh://aur@aur.archlinux.org/dcr.git`
