enricobuehlerandClaude Opus 4.8 63efe0ecd5 feat(host/hooks): per-app prep/undo commands (M2b — Sunshine prep-cmd parity) ...

`prep: [{"do": …, "undo": …}]` arrays on GameStream apps.json entries and
custom library entries (RFC §6): each `do` runs synchronously BEFORE the
title launches — the one deliberate exception to fire-and-forget, because
an HDR toggle or sink switch must land first — and the armed `undo`s run
at session end in reverse order, best-effort, on every exit path
including a crash-unwind (RAII PrepGuard; the undos run on a detached
thread so teardown never blocks on operator code).

- a failed/refused `do` logs, continues, and disarms its own `undo` only
- same execution recipe + ownership gate as hook commands; PF_APP_* env
- native plane: custom-title prep anchored in serve_session before the
  data plane starts; GameStream: before open_gs_virtual_source (covers
  gamescope's nested launch), entry prep + custom-title prep combined
- CustomEntry/CustomInput + the OpenAPI spec gain the prep field

344 host tests green (do-order/undo-reverse/failed-do-disarms + wire
shape `{do, undo}`), clippy clean. On-glass with a real client session
owed.
