feat: Enhance dependency management and project setup

- 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.
