Pull Request Overview

This PR implements rich tool UI support for the Python querychat package, replacing basic text-based tool outputs with interactive buttons and enhanced visual feedback. The main changes include switching from Shiny's basic chat UI to shinychat's rich tool display system, and adding a new tool for resetting dashboard filters.

• Adds rich tool UI with interactive buttons using shinychat and updated chatlas dependency
• Introduces a reset dashboard tool for easy filter clearing
• Refactors tool functions into a separate module with enhanced visual feedback
