docs: Campaign LA Linux posture — full launcher stack Linux-tested; GUI waits for Slice L

User decision 2026-08-14: everything the launcher does ships Linux-tested
in this campaign (launcher UI, install/update with manual DAT picker,
headless launches with plugins + login commands, probe, per-slice Linux
test runs, Linux connected-gate section at LA11). GUI client launches
stay Windows-only until Slice L resumes later; the launcher renders GUI
modes disabled on Linux with an explicit note, and the host-agnostic
session-config contract means Slice L lights them up with no launcher
changes.

## Linux posture (binding — user decision 2026-08-14)
Everything the launcher does must WORK ON LINUX in this campaign, except
GUI client launches: the Linux graphical client is Slice L, parked at L1,
resuming later ("ok we will do it later"). Concretely:
- **Linux-shipping in LA:** the Avalonia launcher UI, profile CRUD +
0600-permission file, installer (manual DAT picker — the auto-detect
paths are Windows-only; `acdream-bake` is GL-free and runs on Linux),
updater (staged swap; Linux can replace a running binary but keep the
same staged-atomic flow), headless launches with plugins + login
commands, and the character probe.
- **Launcher UX on Linux:** the `gui` / `guiSelect` launch modes render
disabled with an explicit "requires the Linux graphical client (Slice
L)" note — never a silent failure.
- **Per-slice enforcement:** every slice touching Launcher.Core, Headless,
Runtime, Bake, or Platform runs its test projects on Linux (native
Ubuntu or WSL, matching the K-slice practice) before the slice is DONE;
LA4/LA9/LA10 additionally prove a real `linux-x64` self-contained
publish. LA11's connected-gate script gets a Linux section: launcher on
Ubuntu doing CRUD, probe, headless launch with plugin + login commands,
first-run install with a manual DAT path, and an update swap.
- When Slice L later ships, the launcher's Linux GUI modes light up with
NO launcher changes (the session-config contract is host-agnostic) —
that expectation is part of LA's design acceptance.
