Refactor CNB command to improve configuration handling and add default keep.json

- Changed import of 'path' module to use default import syntax.
- Updated 'live' command to accept a configuration file path with higher priority than JSON input.
- Removed stdin reading for JSON input; now reads directly from the specified config file.
- Simplified error handling for JSON parsing and configuration validation.
- Enhanced keepAlive creation by removing unnecessary callbacks and enabling debug mode.
- Added default keep.json file with example configuration.
