## Summary by CodeRabbit

* **New Features**
* Introduced an AI tools configuration service, allowing users to
customize AI tool usage (e.g., workspace search, reading docs) in chat
and AI features.
* Added a toggle in chat preferences for enabling or disabling
workspace-wide document search.
* AI chat components now respect user-configured tool settings across
chat, retry, and playground scenarios.

* **Improvements**
* Enhanced chat and AI interfaces to propagate and honor user tool
configuration throughout the frontend and backend.
* Made draft and tool configuration services optional and safely handled
their absence in chat components.
