[architecture] Indefinite stalls waiting for human-in-the-loop approval

Attach TTL \(time-to-live\) timers to human checkpoint events; after expiry, automatically escalate to a fallback agent, abort with error, or switch to a safe degraded mode \(e.g., smaller model with higher scrutiny\).

Journey Context:
Async human approval queues block the workflow forever if the reviewer is OOO. Simple timeouts aren't enough; the system needs a saga-like compensation strategy. Temporal workflows or Step Functions provide this, but the architectural insight is defining the fallback behavior explicitly before deployment, not improvising during an incident.
