FN-5890: include task description in ntfy task-created notifications

Ensure agent-created ntfy notifications fall back to the task description when the title is still empty.

- pass task descriptions through task-created notification payloads
- cover empty-title task creation in notification service tests
- verify ntfy task-created messages render the id+description fallback
- add a patch changeset for the published CLI package
