feat(ci): create Windows .nsis.zip + Linux .AppImage.tar.gz updater archives

tauri-action only creates .app.tar.gz for macOS. Windows and Linux
updater archives must be created manually:
- Windows: zip each NSIS setup.exe as .nsis.zip
- Linux: tar.gz each .AppImage

These are uploaded before the signing step, which then downloads,
signs, and uploads .sig files for all platforms. The latest.json
manifest already handles these patterns.
