* feat(cron): add failure destination support with webhook mode and bestEffort handling
Extends PR #24789 failure alerts with features from PR #29145:
- Add webhook delivery mode for failure alerts (mode: 'webhook')
- Add accountId support for multi-account channel configurations
- Add bestEffort handling to skip alerts when job has bestEffort=true
- Add separate failureDestination config (global + per-job in delivery)
- Add duplicate prevention (prevents sending to same as primary delivery)
- Add CLI flags: --failure-alert-mode, --failure-alert-account-id
- Add UI fields for new options in web cron editor
* fix(cron): merge failureAlert mode/accountId and preserve failureDestination on updates
- Fix mergeCronFailureAlert to merge mode and accountId fields
- Fix mergeCronDelivery to preserve failureDestination on updates
- Fix isSameDeliveryTarget to use 'announce' as default instead of 'none'
to properly detect duplicates when delivery.mode is undefined
* fix(cron): validate webhook mode requires URL in resolveFailureDestination
When mode is 'webhook' but no 'to' URL is provided, return null
instead of creating an invalid plan that silently fails later.
* fix(cron): fail closed on webhook mode without URL and make failureDestination fields clearable
- sendCronFailureAlert: fail closed when mode is webhook but URL is missing
- mergeCronDelivery: use per-key presence checks so callers can clear
nested failureDestination fields via cron.update
Note: protocol:check shows missing internalEvents in Swift models - this is
a pre-existing issue unrelated to these changes (upstream sync needed).
* fix(cron): use separate schema for failureDestination and fix type cast
- Create CronFailureDestinationSchema excluding after/cooldownMs fields
- Fix type cast in sendFailureNotificationAnnounce to use CronMessageChannel
* fix(cron): merge global failureDestination with partial job overrides
When job has partial failureDestination config, fall back to global
config for unset fields instead of treating it as a full override.
* fix(cron): avoid forcing announce mode and clear inherited to on mode change
- UI: only include mode in patch if explicitly set to non-default
- delivery.ts: clear inherited 'to' when job overrides mode, since URL
semantics differ between announce and webhook modes
* fix(cron): preserve explicit to on mode override and always include mode in UI patches
- delivery.ts: preserve job-level explicit 'to' when overriding mode
- UI: always include mode in failureAlert patch so users can switch between announce/webhook
* fix(cron): allow clearing accountId and treat undefined global mode as announce
- UI: always include accountId in patch so users can clear it
- delivery.ts: treat undefined global mode as announce when comparing for clearing inherited 'to'
* Cron: harden failure destination routing and add regression coverage
* Cron: resolve failure destination review feedback
* Cron: drop unrelated timeout assertions from conflict resolution
* Cron: format cron CLI regression test
* Cron: align gateway cron test mock types
