Added:

- `dcr gen` command for IDE integration and build tool support
    - `dcr gen project-info`: Output project metadata as JSON
    - `dcr gen compile-commands`: Generate `compile_commands.json` for clangd and clang-tidy
    - `dcr gen vscode`: Generate VS Code `.vscode/` integration (launch.json, tasks.json, settings.json)
    - `dcr gen clion`: Generate JetBrains CLion `.idea/` integration (run configurations, build targets)
- Full workspace support for all `gen` subcommands
