Auto-continue after a phantom-notification dead-end instead of just warning

Extends the phantom-notification guard: when a non-paired turn dead-ends on an
"I'll wait … I'll be notified" final with no watcher registered, re-invoke the
agent once (inject a corrective nudge as an inbound instruction + re-enqueue) so
it actually finishes the work in the foreground, rather than only appending a
"send a follow-up" notice. A hard per-chat cap (max 1 re-run per phantom streak,
reset on any clean final) makes it loop-safe — a model that keeps producing the
dead-end can never spin the bot. Paired rooms are excluded because they already
continue on their own (owner → reviewer → …). Pure cap/decision logic is unit-
tested; reuses the proven ipc_injected_human + enqueueMessageCheck path.
