Add Forgejo Debian Registry upload using bootc method

- Implement Forgejo Debian Registry API upload following bootc workflow pattern
- Upload libfuse3-3 package directly to Forgejo package registry
- Add proper error handling for different HTTP response codes
- Support both authenticated and unauthenticated upload modes
- Extract package metadata (name, version, architecture) automatically
- Provide clear feedback on upload success/failure
- Include manual upload instructions when no ACCESS_TOKEN is available

This enables automatic package publishing to Forgejo's Debian registry,
making packages installable via 'apt install libfuse3-3' after upload.
