Improve Xcode CLI Tools installation flow

- Add interactive waiting for Xcode CLI tools installation
- User can press Enter after installation completes to continue
- For non-interactive execution: auto-detect installation completion
- Add timeout protection (10 minutes max wait)
- Add retry mechanism with verification
- Better user guidance and progress feedback
