feat(swarm): integrate LLM runner into AgentSwarm.run()

- Make AgentSwarm.run() async with optional enableLLM flag
- Wire runAgentTurn from agent-runner.js into all 4 topologies
  (round_robin, supervisor, dynamic, sleeptime)
- Update drainSleeptimeQueue to use runAgentTurn for actual LLM
  execution instead of passive inbox reading
- Export runAgentTurn, runAgentLoop, runSwarmTurn from uok/index.js
- Update PersistentAgent JSDoc to reflect runner exists
- Fix test imports after extension consolidation (ttsr, google-search)

  * Consumer: AgentSwarm orchestrator, swarm role agents (CoordinatorAgent, WorkerAgent etc),
  * and direct use in multi-agent dispatch flows.
  *
- * ## Current state
+ * ## Runner
- * This module implements the **container** half of a persistent agent: identity, inbox,
+ * The `agent-runner.js` module (sibling to this file) implements the LLM execution half:
- * memory blocks, and message routing. It does NOT implement the **runner** half.
- *
- * The missing piece is an LLM execution runner that:
  *   1. Reads pending messages from this agent's inbox (`receive(true)`)
  *   2. Assembles a prompt from core memory blocks + inbox messages
  *   3. Dispatches to SF headless (`node dist/loader.js headless --print <prompt>`)
  *   4. Writes the LLM response back into the bus as a reply
- *   5. Updates memory blocks (eviction, summarization) when context grows large
+ *   5. Limits context window to the most recent N turns
  *
- * Until the runner exists, `PersistentAgent` is a passive store. The autonomous loop
+ * `AgentSwarm.run()` optionally enables LLM-backed turns via `opts.enableLLM`.
- * uses it this way for sleeptime memory consolidation (caller sends + immediately reads
+ * When disabled, the swarm acts as a pure message router (useful for tests).
- * inbox). `SwarmDispatchLayer` also only enqueues messages — nothing processes them.
- *
- * When building the runner, key design decisions to make:
- *   - Context window management: how many inbox turns to include before summarizing
- *   - Memory eviction: which core blocks are injected, which are summarized to archival
- *   - Turn limits: max rounds before the runner yields and re-queues
- *   - Concurrency: one runner per agent name (enforce via DB lock or process mutex)
- *   - Error handling: failed LLM calls should leave the message as unread, not drop it
  *
  * See: Codex `codex-rs/core/src/agent/control.rs` for the reference implementation of
  * typed parallel subagents (explorer/worker roles) with forked rollout history.
