feat: continue release workflow even if one OS build fails

Changes:
- Added `fail-fast: false` to build-wheels strategy so failing builds don't cancel other OS builds
- Updated publish job to run with `always()` condition so it attempts to publish whatever wheels are available
- Added build status report showing which platforms succeeded/failed
- Download artifacts with `continue-on-error: true` to handle partial failures gracefully
- Exit with error only if no wheels are available at all

This ensures that if e.g. Windows builds fail, Linux and macOS wheels will still be published
