feat: add cleanup option for auto-installed dependencies in build command

- 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.
