Added:

- Full Git dependency support in `dcr.toml`
  - Support for `git`, `branch`, `tag`, and `rev` fields
  - Automatic cloning and checkout via `git2`
  - Dependencies are stored in `target/<profile>/deps/git/`
- New `dcr add` command for easy dependency management
  - Short syntax: `github:user/repo`, `gitlab:user/repo`, `path:/to/lib`
  - Automatic GitHub resolution for `git:user/repo`
- Visual feedback for dependency fetching with in-place status updates ("Fetching" → "Fetched")
- Modular dependency management architecture in `src/core/deps/`
