Module job 

Job state machine and dispatch (RFC §10).

Phase 3 implements the core lifecycle: a tool.invoke envelope is turned into a Job that runs in its own tokio task with a CancellationToken. The runtime emits job.accepted, job.started, then a terminal job.completed / job.failed / job.cancelled.

The heartbeat watchdog and hard-kill escalation that the RFC describes in §10.3 / §10.4 land in a follow-up phase; the cooperative cancel path is in place via CancellationToken.
