- New workflow 'download-artifacts.yml' for downloading artifacts from any run ID
- Supports filtering for *-AnyKernel3 artifacts automatically
- Can upload to latest release or specified release tag
- Includes error handling and detailed summary output
- Usage: Set run_id (e.g., 18696122573) and optionally release_tag
