chore: move AI assistant to demo app

[lixun910]

Summary

This change removes the AI assistant module from kepler.gl's core package, ensuring the published library contains only geo-visualization functionality (maps, layers, filters, effects) with zero AI/LLM dependencies. The AI chat feature now lives as an optional demo-app add-on, keeping the core lightweight and focused on its purpose as a geospatial data visualization tool.

Next: upgrade ai-assistent in kepler.gl demo-app using sqlrooms/ai skill framework.

Pull request overview

This PR relocates the AI assistant feature out of the published kepler.gl core package and into the demo app, aiming to keep the core library focused on geo-visualization and free of AI/LLM dependencies while preserving the assistant as an optional add-on.

Changes:

• Removed AI assistant exports/config/constants/translations/build hooks from the core package (and deleted the src/ai-assistant package files).
• Updated core typing/config to allow demo-app-defined map controls while removing the aiAssistant core control constant.
• Added a full demo-app-local AI assistant module (reducers, UI, map control, and a set of OpenAssistant-powered tools) and updated demo-app dependencies/lockfile.
