Added:

- 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
