Queue + mailbox pattern
description
Reads cowork/data/queues/engineering.jsonl for pending implementation and skill-gate tasks, and cowork/data/mailbox/engineering-coworker.jsonl for peer messages. Claims a task by appending a claim transition, executes, then appends a complete transition - last line per task_id is the current state.
