feat: Implement compose functionality with base image resolution
- Add ComposeManager for handling base image resolution and compose operations - Support multiple base image formats: ubuntu:24.04, debian/12/x86_64, etc. - Implement compose subcommands: create, build-image, list - Add dry-run support for safe testing without OSTree environment - Map base images to OSTree branches: ubuntu:24.04 -> ubuntu/24.04/x86_64 - Support package specification and output branch control - Temporarily disable OSTree validation for compose commands to enable testing This enables the critical path for dogfooding with apt-ostree compose create --base ubuntu:24.04
