Update Debian version recommendations based on current release status

DEBIAN VERSION UPDATES:
- Debian 12 (Bookworm) is now oldstable with outdated OSTree packages
- Debian 13 (Trixie) is now stable and recommended for bootc
- Debian 14 (Forky) is testing with latest OSTree libraries
- Update all Containerfiles to use debian:trixie-slim

OSTREE COMPATIBILITY:
- Document OSTree version requirements for each Debian release
- Add backporting guide for newer OSTree libraries from Forky to Trixie
- Explain benefits of newer OSTree (bootupd support, better bootc compatibility)
- Update compatibility matrix with current Debian status

RECOMMENDATIONS:
- Recommend Debian 13 (Trixie) as minimum for production use
- Suggest Debian 14 (Forky) for latest OSTree libraries
- Provide backporting instructions for Trixie users
- Update testing matrix to reflect current Debian releases

This addresses the critical issue that Debian 12's OSTree packages
are too old for modern bootc/bootupd requirements.

### Prerequisites
- Debian 12 (Bookworm) or later (tested with Bookworm)
- Debian 13 (Trixie) or later (recommended)
- Debian 12 (Bookworm) - oldstable, OSTree packages too old
- Debian 14 (Forky) - testing, has newer OSTree libraries
- Systemd as the init system
- Root access for installation
- Development tools and dependencies for compiling bootc
@ -65,6 +67,11 @@ Converting an existing Debian system to use bootc requires careful planning:
### Debian-Specific Considerations
- **Source Compilation**: Since bootc is not packaged for Debian yet, you'll need to compile from source
- **OSTree Version Requirements**:
- Debian 12 (Bookworm): OSTree packages too old, not recommended
- Debian 13 (Trixie): Has newer OSTree libraries, recommended for bootc
- Debian 14 (Forky): Has latest OSTree libraries, ideal for bootupd/bootc
- **Backporting**: Newer OSTree libraries from Forky can be backported to Trixie
- **Package Management**: bootc works alongside `apt` for application packages while managing the base OS through container images
- **Configuration**: System configuration follows Debian conventions with `/etc` for machine-local settings
- **Services**: systemd services work normally, with bootc managing the base OS layer
