UX: Add clear indicator for conversation end state

[Lcccocoa]

Question

Issue Description

During conversation interactions, users cannot clearly tell when the AI response has finished. This leads to users potentially:

• Being unsure whether they can type the next message
• Mistakenly waiting, thinking the AI is still generating content
• Affected overall user experience

Expected Behavior

The conversation should have clear visual or interactive indicators to let users know:

• The AI is generating a response (loading state)
• The AI has completed the response
• The user can start a new input

Current Behavior

• No clear end marker or indicator
• Users cannot intuitively determine if the conversation is complete
• Lack of visual feedback to distinguish between "generating" and "completed" states

Suggested Solutions

Consider implementing one or more of the following approaches:

1. Visual Indicators

   • Add typing animation or progress indicator showing AI is responding
   • Add special markers at the end of AI responses (e.g., horizontal line, end symbol)
   • Use different colors or styles to distinguish AI response boundaries

2. Interactive Feedback

   • Input box state changes (e.g., disabled/enabled)
   • Cursor state changes

3. Timestamps or Markers

   • Add timestamps at the end of each message
   • Add a "completed" status marker

Environment Info

• Operating System: macOS
• Usage Method: Terminal/Desktop App

Additional Notes

This is a UX/UI improvement suggestion to enhance user interaction experience.

we have an indicator which shows that AI is responding, however, it may not be clear enough (far away from the input)

This is addressed in #10435
