docs(desktop): refresh launch-opt plan pending list with App() blocker

Phase 1.4 / 2.4 / the four Phase 5.2 regression tests are all blocked on
the same broader App() dependency-injection refactor — relayManager,
localCache, localRelayStore, and subscriptionsCoordinator are still
constructed inside App() via remember { … }. The torManager slot has
been loosened to ITorManager in preparation, but the rest is wider work
than this session can absorb.
