feat: implement repository_dispatch for automated desktop builds

- Add desktop build trigger to release workflow when new release is published
- Switch desktop-build workflow from release events to repository_dispatch
- Include clean file filtering to only attach installer files (Setup.exe, .dmg, .AppImage)
- Pass version info through client payload for accurate release targeting
- This enables automatic desktop builds after successful web app releases
