Previously intake-task returned {"status":"queued"} with no task_id,
breaking runbook steps 3-4 that needed the id for transition-task.
Now cmd_intake_task creates the task in the store immediately (like
create-task) and returns the full Task object including id, status,
title, etc. The scheduler queue path is unchanged — the task is still
pushed to the intake queue for the tick to route/claim.
Test updated: scheduler_routes_intake verifies response contains id.
