Improve download system with robust build detection

- Replace hardcoded workflow run IDs with generic Actions tab links
- Add find-latest-build.sh script to automatically detect working builds
- Add download-latest.sh helper script for manual download guidance
- Update README with clear step-by-step download instructions
- Make download system self-maintaining and always accessible
- Provide both automated and manual download approaches

This fixes the broken download links by creating a system that
automatically finds the latest successful build and provides
reliable download instructions that work with Forgejo's artifact system.
