As a user waiting for AI response

I want to see engaging feedback during thinking

So that I know the system is working and don't think it's frozen

Description:
Improve the thinking/loading animation during AI response:

Current: Simple "..." with pulse animation

Improved ideas:

1. Terminal cursor: Blinking cursor effect
2. Typewriter effect: Characters appearing one by one
3. Matrix rain: Subtle falling characters in background
4. Scanning line: Horizontal line moving across message box

Choose one or combine:

• Primary: Typing indicator with cycling dots
• Secondary: Subtle scanline effect on chat box

Tech Notes:

• CSS animations only
• Should not block UI
• Graceful degradation for reduced motion

Story Points: 1

Acceptance Criteria:

• Animation plays during AI response
• Animation stops when response received
• Respects prefers-reduced-motion
