fix(delegation): close the caller loop — default poke-back ON + deliver to a live caller (v0.223.0)

[vikasprogrammer]

The bug

When an agent dispatched a task to another agent (caller → callee), the caller was never notified when the callee finished — you had to manually type "check that task status pls" for it to poll and find out.

Root cause — two compounding gaps

1. The mechanism never engaged. poke_on_done was opt-in and defaulted off, and the live instapods data confirms no agent ever set it — caller_agent is null on every task, and there are zero agent.poked events in the whole audit history. So the caller was never recorded and never woken; only the human owner got a task.notified DM.

2. Even when it fired, a live caller was skipped. pokeCaller skipped delivery when the caller's session was still alive, on the assumption it "will observe the outcome itself." But an interactive/resident caller (the session you're chatting with) sits idle at the prompt after ending its turn — it observes nothing. That's the exact symptom.

The fix

• task_create defaults the async wake ON for an agent→agent hand-off, so the delegation loop closes itself. Opt out with poke_on_done: false; wait: true still supersedes with a synchronous block; a self-assignment never wakes (guarded server-side too).
• pokeCaller delivers into a live caller by injecting the result into its pane (idle → runs now, mid-turn → queues to the next turn boundary) via the same production-proven injectToSession primitive that powers console Quick Shortcuts / deliverToResident — falling back to a --resume only when the caller has already exited.

Verification

• MCP default truth table (agent hand-off ON, opt-out, wait supersedes, self-assign / open / human assignee never wake) — ✅
• Server self-poke guard (cross-agent stamped, self-poke dropped, human not stamped) — ✅
• In-memory TaskStore round-trip: caller fields persist and a done status-notice carries them to maybePokeCaller — ✅
• npm run typecheck clean · npm run build clean · 68/68 governance conformance — ✅
