fix(cron): prevent duplicate proactive delivery on transient retry (#40646)

* fix(cron): prevent duplicate proactive delivery on transient retry

* refactor: scope skipQueue to retryTransient path only

Non-retrying direct delivery (structured content / thread) keeps the
write-ahead queue so recoverPendingDeliveries can replay after a crash.

Addresses review feedback from codex-connector.

* fix: preserve write-ahead queue on initial delivery attempt

The first call through retryTransientDirectCronDelivery now keeps the
write-ahead queue entry so recoverPendingDeliveries can replay after a
crash.  Only subsequent retry attempts set skipQueue to prevent
duplicate sends.

Addresses second codex-connector review on ea5ae5c.

* ci: retrigger checks

* Cron: bypass write-ahead queue for direct isolated delivery

* Tests: assert isolated cron skipQueue invariants

* Changelog: add cron duplicate-delivery fix entry

 ### Fixes
 
+- Cron/proactive delivery: keep isolated direct cron sends out of the write-ahead resend queue so transient-send retries do not replay duplicate proactive messages after restart. (#40646) Thanks @openperf and @vincentkoc.
 - TUI/chat log: reuse the active assistant message component for the same streaming run so `openclaw tui` no longer renders duplicate assistant replies. (#35364) Thanks @lisitan.
 - macOS/Reminders: add the missing `NSRemindersUsageDescription` to the bundled app so `apple-reminders` can trigger the system permission prompt from OpenClaw.app. (#8559) Thanks @dinakars777.
 - iMessage/self-chat echo dedupe: drop reflected duplicate copies only when a matching `is_from_me` event was just seen for the same chat, text, and `created_at`, preventing self-chat loops without broad text-only suppression. Related to #32166. (#38440) Thanks @vincentkoc.
