CVE-2026-44999: OpenClaw: Isolated cron awareness events were recorded as trusted system events

Output from webhook-triggered isolated cron agent runs could be queued into the main session awareness stream without trusted: false. That made the event render as a trusted System: event instead of an untrusted system event.

This is a trust-labeling issue that can strengthen prompt-injection impact, but it does not directly bypass gateway auth, tool policy, or sandboxing. Severity is low.
