refactor: move version to separate module and improve logging

- Created aitbc/_version.py with centralized version definition
- Updated aitbc/__init__.py to import __version__ from _version module
- Updated constants.py to use __version__ for PACKAGE_VERSION
- Replaced print() calls with logger in decorators.py, events.py, queue_manager.py, and state.py
- Added logger initialization using get_logger(__name__) in config.py, decorators.py, events.py, queue_manager.py, and state.py
- Added cli/commands
