Summary

Script cron jobs (payload.kind: "script") currently run via execCronScript and return a bare CronRunOutcome with no delivered/deliveryAttempted fields. The announce/delivery pipeline is never invoked.

Problem

agentTurn jobs get delivery via runIsolatedAgentJob which bundles the full run + announce in one dep call. There is no equivalent dep for script output delivery. As a result, --announce / --channel / --to flags are accepted at CLI creation time but silently have no effect at runtime.

Acceptance Criteria

• A new CronServiceDeps function (e.g. sendCronScriptResult) allows delivering script stdout to a configured channel
• executeJobCore calls it after execCronScript returns when delivery is requested
• delivered and deliveryAttempted are correctly populated in the returned result
• Existing script jobs without delivery config are unaffected

Implementation Plan

1. Add sendCronScriptResult (or similar) to CronServiceDeps in state.ts
2. Implement the dep in the gateway (reuse announce machinery from isolated job delivery)
3. In executeJobCore, after execCronScript, call the dep when resolveCronDeliveryPlan(job).requested
4. Return { ...scriptResult, delivered, deliveryAttempted } from the script branch

Files Affected

• src/cron/service/state.ts — new dep
• src/cron/service/timer.ts — call dep after execCronScript
• Gateway wiring (wherever runIsolatedAgentJob dep is implemented)
