Description

Debounce rapid events (search typing, scroll position tracking) to reduce state updates and re-renders, keeping UI responsive.

Current Behavior

Every keystroke/scroll event triggers immediate state update and re-render

Expected Behavior

Events debounced to max 10/second, preventing render spam

Impact

⚡ UI remains responsive during rapid input
📊 Reduced re-render cascades
🎬 Smooth typing/scrolling experience

Acceptance Criteria

• Add debounce helpers for input events
• Debounce search input updates (300ms)
• Debounce scroll handlers (100ms)
• Test: UI stays responsive during rapid input
• Measure re-render reduction
• Document debounce strategy

Implementation Hints

Create useDebounce hook. Use in search input onChange. Apply to scroll listeners.
