feat(FN-3464): wire shared state in peer exchange service (FN-3464 Step 1)

Merges peer exchange shared state wiring (FN-3464) into the engine with updated tests, adds immediate wake controls for agent inbox and message API (FN-3087), and restores the narrow logs/system mouse auto-toggle policy with CLI documentation (FN-3708). Dependency graph plugin receives test and high
