Subject: [PATCH] feat(hooks): restrict background_task for task tool subagents
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- All subagents: disable background_task to prevent recursive spawning
- explore/librarian: additionally disable call_omo_agent
- Ensures task-invoked subagents use call_omo_agent instead of background_task
