Polish pass hardening the queue and closing plan gaps. - Task state machine gains `running`: the first heartbeat moves a task from leased to running (migrations 0006/0007 add the enum value and extend the lease-integrity check). verifyLease, ExpireLease, the reaper SQL, and job progress all treat leased and running alike. - Worker liveness: a heartbeat from a registered worker (UUID worker_id) bumps its last_heartbeat_at online; a second background reaper marks workers offline after WORKER_OFFLINE_AFTER of silence (RunReaper generalized to RunPeriodic). - Request-size limits: JSON bodies capped at 1 MiB; dataset/artifact uploads capped at MAX_UPLOAD_BYTES (default 1 GiB) via http.MaxBytesReader. - Tests cover the running transition, liveness + offline reaper (unit over memstore and integration over Postgres).
