✨ Implement dynamic version loading system

- Convert all hardcoded versions to dynamic loading from VERSION file
- Reduce version update locations from 50+ to just 3 files
- Add proper fallback handling for version reading
- Update all CLI commands to use dynamic __version__
- Streamline future version management process

This change makes version bumping much simpler - only need to update:
1. VERSION file
2. package.json
3. pyproject.toml
