feat(cron): unattended-run preamble and watcher-authoring guidance (#110949)

* feat(cron): add unattended-run preamble to isolated agent turns

Isolated cron and hook agent turns received only the job tag, message,
and time line — no operating contract for unattended execution. Runs
ended in questions, plans, or bare acknowledgements (the runtime even
re-prompts once for interim acks). Append a static per-class preamble:
the final reply is the deliverable, HEARTBEAT_OK when idle, plain
failure statements. Trusted jobs additionally defer to the job's own
instructions on conflict and learn removal-only self-cleanup;
external-hook runs get only the common core so fenced webhook content
cannot use an override clause or a destructive affordance advertised in
the trusted suffix. Free-form job names stay out for the same reason.

* feat(cron): teach watcher authoring rules in the cron tool description

Trigger-script guidance covered only the return contract. Add the
operating rules that keep watchers trustworthy: fire on every
actionable state including failures (success-only watchers go silent
when broken), dedupe via returned state, keep scripts read-only with
actions in the payload, and make the fired message self-contained.

Shanghai 18:00: {kind:\"cron\",expr:\"0 18 * * *\",tz:\"Asia/Shanghai\"}.\n\nTRIGGER SCRIPT:\n- Requires cron.triggers.enabled; if off, explain and never model-poll fallback.\n- Headless owner allowlist; quiet check has no model. Prior trigger.state is frozen JSON. Return/json({fire:boolean,message?:string,state?:JSONValue}); create new state, never mutate prior.\n- fire:false saves state only; no payload/history. fire:true runs payload and appends message; fired state saves only after payload success.\n- Fire on every actionable state, including failures/timeouts; success-only watchers go silent when broken, which looks healthy. Dedupe by comparing trigger.state and returning new state, never memory.\n- Keep scripts read-only; actions belong in payload. message must be self-contained: it is the fired run's entire context.\n- Silent watcher: top-level delivery.mode=\"none\". Omitted delivery on isolated agentTurn announces and missing route may fail.\n- once:true disables after first successful fire. Per check: 30s, 5 tool calls, 16KB state.\n- Hidden Code Mode tools: await tools.call(\"exec\", {command:\"...\"}); unknown id => search/describe.\n\nDELIVERY top-level: {mode:\"none|announce|webhook\",channel?,to?,threadId?,bestEffort?}\n- Isolated agentTurn omitted delivery => announce. announce only isolated/current/session; channel/to optional; threadId chat topic. Specific chat: set channel/to; no messaging tool inside run.\n- webhook posts finished-run event to URL in to.\n\nRestricted isolated runs may only self status/list, current get/runs, and remove current job. wake mode: next-heartbeat default | now. jobId canonical; id compat. contextMessages 0-10 adds prior messages.",
