Pull request overview

Fixes the failing js-typecheck job by updating the JSDoc return type of loadMissingToolMessages in handle_agent_failure.cjs to include the denied_commands field that the function actually returns. This aligns the type declaration with consumers like buildPermissionDeniedContext that read denied_commands from the returned items.

Changes:

• Add denied_commands: Array<string> to the documented return type of loadMissingToolMessages.
