- Introduced a new `cleanup_deps` flag in the build command to remove dependencies that were automatically installed during the build process.
- Implemented an `InterruptWatcher` to handle Ctrl-C interruptions gracefully during the build process.
- Enhanced the `AutoInstalledDependencyTracker` to track and manage auto-installed dependencies, allowing for cleanup after the build.
- Updated the CLI to parse the new `cleanup_deps` flag and integrated it into the build workflow.
- Added tests to ensure the correct parsing of the `cleanup_deps` flag and the functionality of the dependency tracking and cleanup process.
- Improved logging for package removal operations to include a verbose mode controlled by the `DEPOT_VERBOSE_REMOVE` environment variable.
- Added StateTracker to manage build steps and allow resuming interrupted builds.
- Updated post_extract function to utilize StateTracker for patch and command execution.
- Introduced makefile.rs to handle building and installing packages via Makefile.
- Created interactive.rs for an interactive package specification creator with SHA256 computation for source URLs.
- Enhanced checksum verification to support multiple algorithms (SHA256, SHA512, MD5).
- Added example configuration files in contrib for system-wide and user-level Depot configurations.
- Updated tests to cover new functionality and ensure correctness of state tracking and interactive creation.
