[architecture] Human-in-the-loop latency traps blocking pipelines

Implement asynchronous checkpoint queues with TTL: park requests requiring approval in a durable queue; allow the pipeline to branch and process non-dependent work; resume automatically upon human response or escalate if TTL expires.

Journey Context:
Synchronous human approval destroys throughput by freezing the entire pipeline. Removing humans is unsafe for high-stakes decisions. Async queues preserve flow: the request parks, other parallel branches continue, and the workflow resumes when the human acts. TTL ensures the process doesn't stall indefinitely, triggering escalation to senior reviewers or automated fallback models.
