   * outbound payload, and the same value `agent_end`/`llm_input`/`llm_output`
   * fire with. Plugins correlating per-turn state across `agent_end` and
   * `message_sending` rely on this equality.
   *
   * For inbound message hooks (`inbound_claim` etc.), this is the canonical
   * session for the inbound conversation as resolved by `resolveSessionKey`
   * / `deriveInboundMessageHookContext`.
   *
   * For outbound delivery hooks (`message_sending` and `message_sent`),
   * this mirrors `OutboundSessionContext.key` from the dispatch path when
   * delivery has a session attached. When the outbound path has no
   * resolvable session (e.g. internal smoke runs without
   * `OutboundSessionContext`), this field is omitted; plugins must treat
   * it as optional.

  /**
   * Per-turn run identifier (UUID), unique to one end-to-end agent turn:
   * stable across all LLM-call iterations, retry attempts (compaction,
   * empty-response, planning-only, etc.), and multi-payload reply chunks
   * within that turn; distinct for each new inbound user message and for
   * each cron/heartbeat/followup-triggered run.
   *
   * Generated once in `agent-runner-execution.ts`/`followup-runner.ts` via
   * `crypto.randomUUID()`. Currently populated for inbound message hooks
   * (`inbound_claim`, `message_received`) and for agent-runtime hooks that
   * already receive the run id (e.g. `agent_end`, `llm_input`, `llm_output`).
   * It is **not yet** plumbed through the outbound delivery path, so
   * plugins observing `message_sending` / `message_sent` should not rely
   * on `runId` to correlate against `agent_end`; use `sessionKey` for
   * outbound→inbound correlation today (with the caveat that it cannot
   * disambiguate concurrent turns in the same session).
