    Add composefs CI workflow and Dockerfile
    
    - Create Dockerfile for building composefs with meson/ninja
    - Add comprehensive CI workflow based on bootupd-sdboot
    - Includes apt-cacher-ng support for faster builds
    - Builds composefs from source with FUSE support
    - Creates Debian package with proper dependencies
    - Uploads to Forgejo Debian Registry
    - Uses docker cp to transfer files from container to host
