fix: address PR review feedback from Gemini Code Assist

Address three issues identified in code review:

1. Fix missing thinkingLevel parameter (Critical)
   - Added thinkingLevel parameter to enhance API call
   - Updated electron.ts type definition to match http-api-client
   - Fixes functional regression in Claude model enhancement

2. Refactor dropdown menu to use constants dynamically
   - Changed hardcoded DropdownMenuItem components to dynamic generation
   - Now iterates over ENHANCEMENT_MODE_LABELS object
   - Ensures automatic sync when new modes are added
   - Eliminates manual UI updates for new enhancement modes

3. Optimize array reversal performance
   - Added useMemo hook to memoize reversed history array
   - Prevents creating new array on every render
   - Improves performance with lengthy histories

All TypeScript errors resolved. Build verified.
