"""DB-backed OpenClaw orchestration and agent lifecycle services.

Layering:
- `app.services.openclaw.provisioning` contains gateway-only lifecycle operations (no DB calls).
- This module builds on top of that layer using AsyncSession for token rotation, lead-agent records,
  bulk template synchronization, and API-facing agent lifecycle flows.
