feat: Add installation of Linux cross compilation tools for builds

- Added support for registry-based dependencies in the dependencies section.
- Updated the package section to include a project type field.
- Introduced a new CLI command `dcr setup` to load and display registry configurations.
- Implemented a new module for handling registry operations, including loading and resolving packages from registries.
- Enhanced the build process to handle library packaging, including copying headers and libraries to the appropriate target directories.
- Updated the CLI to support building library packages and added tests for library package builds.
- Improved error handling and output messages during dependency resolution and package fetching.

 ### Key Concepts
 
-- **`dcr.toml`** — конфигурационный файл проекта (аналог `Cargo.toml`). Секции: `[package]`, `[build]`, `[toolchain]`, `[dependencies]`, `[workspace]`.
-- **Профили сборки**: `debug` (по умолчанию) и `release`. Встроенные флаги зависят от компилятора. Пользовательские флаги через `build.cflags` / `build.ldflags`.
-- **Инкрементальная сборка**: объектные файлы кешируются по mtime. Отслеживание заголовков пока не реализовано (см. `TODO.md`).
-- **Workspace**: корневой `dcr.toml` с секцией `[workspace]` описывает member-проекты и их зависимости; сборка происходит в топологическом порядке.
-- **Path dependencies**: зависимости по путям автоматически добавляют include/lib-пути; генерируется `dcr.lock`.
-- **Build kinds**: `bin` (бинарник), `staticlib` (`.a`), `sharedlib` (`.so`/`.dylib`/`.dll`).
+- **`~/.dcr/`**: Centralized storage for registries and configurations.
+- **`config.toml`**: File in `~/.dcr/` defining available package indices and their priorities.
+- **`dcr.toml`**: Local project configuration.
+- **Registry System**: `RegistryManager` handles package discovery across multiple indices based on priority.
