log(feat[simple-formatter]): Add clean output formatter for CLI add commands

why: CLI add/add-from-fs commands should have clean output like print() while preserving debug output for VCS operations.
what:
- Add SimpleLogFormatter that outputs only the message without extra formatting
- Configure specific loggers for vcspull.cli.add and vcspull.cli.add_from_fs to use simple formatter
- Keep DebugLogFormatter for vcspull core operations and sync commands
- Prevent logger propagation to avoid duplicate output
- Maintain detailed VCS operation logging for sync functionality
