Enhancement: Add AI response loading indicator for better UX

[madhavansingh]

Problem

When a query is submitted the interface waits silently while the AI generates the response. Users may think the app is stuck.

Proposed Enhancement

Add a loading indicator (spinner or "AI is thinking...") that appears while the AI response is being generated and disappears when the response arrives.

I am exploring Liquid Galaxy while preparing for Google Summer of Code 2026 and would love to contribute improvements like this.

Hi! This PR implements the loading indicator feature discussed in the issue. The goal is to improve user feedback while the AI response is being generated.

Please let me know if any adjustments or improvements are needed. I would be happy to update the implementation.
