On first launch O3DE pip-installs its 'o3de' CLI with 'pip install -e'
(editable), which writes an egg-info next to the source under read-only
/app and fails ([Errno 30] Read-only file system), leaving the venv broken
("unable to install O3DE's built-in Python").
- Patch cmake/LYPython.cmake at build time to force a normal (non-editable)
install, which builds in a temp dir and lands in the writable ~/.o3de venv.
- Drop the build-time get_python "bake": the venv is per-user (keyed to
$HOME), so it can only be created at runtime; baking under a throwaway
build HOME did nothing. Speeds up CI; removes cmake/python3 build deps and
the network build-arg.
- Add a real launcher icon (org.o3de.O3DE.png).

O3DE's bundled Qt only ships the xcb platform plugin, so it needs X11/
XWayland. Using --socket=fallback-x11 alongside --socket=wayland meant X11
was not shared on Wayland sessions, leaving DISPLAY empty and Qt unable to
connect. Share --socket=x11 unconditionally instead.

Inspecting o3de_2605_0.deb (control.tar md5sums) showed:
- everything installs under /opt/O3DE/<ver>/; no /usr glue, no app icon
- ~270 .so files sit beside the o3de launcher (LD_LIBRARY_PATH is required)
- the package depends on a build toolchain (clang/ninja/cmake/pkg-config)
- no Python runtime is bundled; O3DE fetches it into its install tree on
first use, which is read-only in a Flatpak
Changes:
- run against org.freedesktop.Sdk so the build toolchain is present at runtime
- bake O3DE's Python in at build time via get_python.sh (network build-arg)
- drop the icon auto-grab (it would have installed a random asset SVG)
- document the remaining open risk: runtime writes into the read-only /app

Repackage the official O3DE Linux .deb as a Flatpak and publish it as a
static OSTree repo on the 'pages' branch for install via flatpak remote.
- org.o3de.O3DE.yaml: flatpak-builder manifest (extracts the .deb into /app)
- o3de-wrapper.sh: launcher that locates the versioned o3de binary at runtime
- desktop + AppStream metadata under the app-id
- scripts/: live version resolver and local build helper
- .gitea/workflows/build-flatpak.yml: daily check -> build -> publish -> tag
