feat(version): enhance version detection and display across sidecar and binary installations

- Implement regex-based version extraction for more reliable parsing
- Add version detection for bundled sidecar installations with proper execution
- Improve version checking for sidecar binary with timeout and error handling
- Update UI to display version with "v" prefix for consistency
- Add comprehensive logging for version detection debugging
- Handle edge cases in version extraction with fallback mechanisms
