Add window size animation for Settings and build script for tty-fwd

- Implement smooth window size animations when switching Settings tabs
- Add Xcode build phase to automatically build tty-fwd universal binary
- Configure build script with proper input/output dependencies for efficiency
- Fix Settings window animation using NSViewAnimation API
- Update project configuration for optimized builds
