teknium1 98fe6d0a8e fix(delegation): integrate lifecycle refactor with tool-history + daemon pool
Follow-ups on the salvaged #63359:
- _finalize_child_results carries tool_call_history on subagent_stop
  (the #62011/#72403 field landed after the PR branched; the shared
  pipeline must emit it for both delegate_task and plugin-launched
  children). Lifecycle test updated for the new payload field.
- The lifecycle executor uses DaemonThreadPoolExecutor — a wedged or
  abandoned child must never block interpreter exit at atexit-join time
  (same rationale as _run_single_child's timeout executor and the
  async-delegation pool).
- delegate_task's batch path keeps live-transcript wiring while routing
  child construction through the shared
  _build_child_preserving_parent_tools helper.
