-- `ctx.agentLoop.create(id: string, options?: AgentOptions): ReactLoopAgent` — config-driven create: an agent on a fresh per-run session id `${id}-session-<uuid>` (no cwd). Used for `cordis.yml`-configured agents. The per-run uuid avoids colliding with the on-disk log a prior run materialized once a durable persistence backend is loaded; each run is a new session (a deliberate demo simplification — a real resume-or-create policy is a TODO). Disposed with the calling fiber.

 `AgentLoop` also implements the `AgentFactory` seam and registers itself via `ctx.agents.setFactory(this)`, so plugins create/resume agents through `ctx.agents` (the interface):
