34aa70cbd9 feat(workflows): TaskExecutorWorkflow stub + wire worker — T19/T20 
activities.py — persist_task_instance (new):
  Idempotent INSERT ... ON CONFLICT (id) DO NOTHING on task_instances.
  task_id passed in from workflow (derived from workflow_id via uuid5).
  Registered on task-execution-tq.

workflows.py — TaskExecutorWorkflow (T19):
  Derives stable task_id = uuid5(NAMESPACE_URL, workflow_id).
  Calls persist_task_instance → status=done, returns immediately.
  Real execution logic to replace stub in a later workstream.

worker.py — T20:
  Registers persist_task_instance on task-execution-tq Worker.
  Both queues fully wired: orchestrator-tq and task-execution-tq.

da7de6ea3b feat(workflows): implement RunActivityWorkflow — T18 
workflows.py — RunActivityWorkflow:
  1. load_activity_definition(activity_id)
  2. resolve_context(context_sources)
  3. evaluate_templates (pure, called in-workflow)
  4. log_run({run_id, ...}) — run_id = uuid5(NAMESPACE_URL, activity_id:trigger_key)
  5. start_child_workflow(TaskExecutorWorkflow, ...) per task spec
     ABANDON parent-close policy (fire-and-forget)
  Returns {"run_id": str, "tasks_spawned": int}

activities.py — log_run updated:
  - now accepts run_id in run_payload (deterministic, passed from workflow)
  - uses pg INSERT ... ON CONFLICT (run_id) DO NOTHING for idempotency

21edc313db feat(worker): scaffold activities, workflows, worker entrypoint — T13 
src/activity_core/activities.py:
  - load_activity_definition, resolve_context, log_run — @activity.defn
    stubs (raise NotImplementedError, bodies in T14–T17)

src/activity_core/workflows.py:
  - RunActivityWorkflow (orchestrator-tq) — @workflow.defn stub (T18)
  - TaskExecutorWorkflow (task-execution-tq) — @workflow.defn stub (T19)

src/activity_core/worker.py:
  - Connects to Temporal via TEMPORAL_HOST / TEMPORAL_NAMESPACE env vars
  - Spawns two Workers: orchestrator-tq and task-execution-tq
  - Runs until cancelled (python -m activity_core.worker)
