Add bazzite, bazzite-deck, batocera distro support (#20)

Each distro ships with a self-contained build-rootfs.sh that the entrypoint
calls in place of distrobuilder.  This keeps upstream's distrobuilder flow
untouched for the existing distros (ubuntu/arch/cachyos/fedora/etc.) and
isolates the new distros' build logic in their own dirs.

distros/bazzite/
  build-rootfs.sh — skopeo+umoci on ghcr.io/ublue-os/bazzite:stable,
                    promote ostree /usr/etc -> /etc, install linux-ps5 RPM,
                    mask rpm-ostree services, set up grow-rootfs + DTM-TA
                    amdgpu reprobe.
  image.yaml, grow-rootfs, grow-rootfs.service

distros/bazzite-deck/
  Symlinks into distros/bazzite/ — bazzite-deck shares all build logic;
  the case branch in build-rootfs.sh dispatches via $DISTRO.

distros/batocera/
  build-rootfs.sh — download upstream batocera-x86_64-*.img.gz, mount,
                    extract /boot/batocera squashfs, swap in linux-ps5
                    kernel, patch libretroControllers.py, install first-boot
                    SHARE-partition creator (ps5-share-init).

docker/image-builder/entrypoint.sh
  - detect_kver() helper from /kernel-debs/ package filenames
  - dispatch to distros/$DISTRO/build-rootfs.sh when present (skips
    distrobuilder for that distro)
  - EFI assembly detects /boot/efi/ vs /boot/bzImage layouts so batocera
    (which mounts FAT at /boot, not /boot/efi, for batocera-part SHARE
    detection) works alongside the standard layout

build_image.sh
  - IMG_SIZE defaults: bazzite* -> 24 GB, batocera* -> 16 GB
  - FORMAT: bazzite* -> rpm (linux-ps5 RPM); batocera* stays deb

CI workflows are NOT modified — the upstream build-image.yml /
trigger-builds.yml continue to apply and will skip these distros unless
explicitly dispatched (they're not in MULTI_DISTROS).  Local builds:
  ./build_image.sh --distro bazzite
  ./build_image.sh --distro bazzite-deck
  ./build_image.sh --distro batocera

+# bazzite / bazzite-deck
+
+Adds support for [Bazzite](https://bazzite.gg/) (uBlue's gaming-focused
+atomic Fedora) and Bazzite-Deck (Steam Deck UI variant) on PS5 hardware.
+
+These are **OCI atomic images** — distrobuilder doesn't apply.
+`distros/bazzite/build-rootfs.sh` runs in place of the distrobuilder call:
+
+1. `skopeo copy docker://ghcr.io/ublue-os/bazzite:stable` → OCI archive
+2. `umoci unpack` → flat rootfs into `$CHROOT`
+3. Promote `/usr/etc` defaults into `/etc`
+4. Install the linux-ps5 RPM via `rpm-ostree`/`dnf`, then mask the
+   rpm-ostree services (we're a flat fs now)
+5. Set up grow-rootfs systemd unit + DTM-TA-race amdgpu reprobe udev rule
+
+`bazzite-deck` is built from `ghcr.io/ublue-os/bazzite-deck:stable` via the
+same script (the `case "$DISTRO" in bazzite-*)` branch generates the OCI
+reference automatically).  All `distros/bazzite-deck/*` files are symlinks
+into `distros/bazzite/`.
+
+## Build locally
+
+```bash
+./build_image.sh --distro bazzite
+./build_image.sh --distro bazzite-deck
+```
+
+Image size bumped to 24 GB (default).  Compressed output is large (~3-5 GB
+`.img.xz`) — too big for a 2 GB GitHub release asset, so this image is not
+auto-published by the CI workflow.
