NOISSUE Refactor UpdateChecker and add standalone updater

- Removed unused member variables and methods from UpdateChecker.
- Improved update checking logic by parsing both RSS feed and GitHub releases.
- Introduced Installer class for handling update downloads and installations.
- Added support for various archive formats (.zip, .tar.gz) in Installer.
- Created meshmc-updater executable for standalone update operations.
- Updated CMake configuration to include new updater components.
