Merges five features: **Launch mode persistence** (FN-3405) — desktop now remembers and restores the user's preferred window mode across restarts via an IPC bridge; **Mailbox detail pane** (FN-3719/3720) — clicking messages in the Mail tab and Mailbox opens the detail pane and reply panel; **Remote
Fusion-Task-Id: FN-3405
- Add ChatStore mock to all dashboard route tests that mock @fusion/core,
since server.ts now instantiates ChatStore(store.getFusionDir(), ...)
- Add getFusionDir to createMockStore in server.test.ts
- Gate AI session cleanup scheduling behind shouldScheduleAiSessionCleanup()
(returns false in test env) to prevent open handle warnings
- Fix desktop tests: DASHBOARD_URL is now exported as a function alias,
update assertions to call DASHBOARD_URL() instead of using as string
- Add node:os mocks to system-metrics.test.ts for deterministic results
- Replace hardcoded maxWorkers=16 with availableParallelism()-based
calculation in all vitest configs to prevent OOM on 2-core CI runners
- Add --workspace-concurrency=2 to pnpm test commands
- Fix TaskCard tests: update mission badge title assertions to full titles
- Remove unused /api/mesh/state route
- Fix plugin-auto-label: add isError field, async onTaskCreated, "tests" keyword
- Fix plugin-ci-status: add module-level logger, tighten test assertions
