Add full iOS build system: script, npm integration, and documentation

- Implement scripts/build-ios.sh with dev/test/prod, IPA, deploy, and Xcode support
- Integrate all iOS build and legacy scripts into package.json (including deploy)
- Update docs/ios-build-scripts.md: mark as complete, add usage and status
- Update README.md: add iOS to quick start, platform builds, and docs links
- Ensure iOS build system matches Android/Electron pattern for consistency

-## Electron Build Scripts
+## Build Systems
 
-### **Development vs Package Builds**
+TimeSafari supports comprehensive build systems for all platforms with unified patterns and consistent tooling.
 
-- **Development Scripts**: Run the app directly after building
-  ```bash
-  npm run build:electron:dev    # Runs app immediately
-  npm run build:electron:test   # Runs app immediately
-  ```
+### **Quick Start Commands**
 
-- **Package Scripts**: Create executable files for distribution
-  ```bash
-  npm run build:electron:appimage  # Creates AppImage executable
-  npm run build:electron:deb       # Creates DEB package
-  npm run build:electron:dmg       # Creates DMG package
-  ```
+```bash
+# Web Development (starts dev server)
+npm run build:web:dev
 
-See [Electron Build Scripts Guide](docs/electron-build-scripts.md) for complete details.
+# Android Development (builds debug APK)
+npm run build:android:dev
+
+# iOS Development (builds debug app)
+npm run build:ios:dev
+
+# Electron Development (runs app directly)
+npm run build:electron:dev
+
+# Deploy Android to connected device
+npm run build:android:deploy
+
+# Deploy iOS to connected device
+npm run build:ios:deploy
+```
+
+### **Platform-Specific Builds**
+
+#### **Web Builds**
+- **Development**: Hot reload server at http://localhost:8080
+- **Production**: Optimized static files with PWA support
+- **Docker**: Containerized deployment images
+
+```bash
+npm run build:web:dev      # Development server
+npm run build:web:prod     # Production build
+npm run build:web:docker:prod  # Docker deployment
+```
+
+#### **Android Builds**
+- **Development**: Debug APK with development optimizations
+- **Production**: Release APK/AAB for app store distribution
+- **Deployment**: Direct installation to connected devices
+
+```bash
+npm run build:android:dev      # Development build
+npm run build:android:prod     # Production build
+npm run build:android:deploy   # Build and deploy to device
+```
+
+#### **iOS Builds**
+- **Development**: Debug app with development optimizations
+- **Production**: Release app/IPA for app store distribution
+- **Deployment**: Direct installation to connected devices
+
+```bash
+npm run build:ios:dev          # Development build
+npm run build:ios:prod         # Production build
+npm run build:ios:deploy       # Build and deploy to device
+```
+
+#### **Electron Builds**
+- **Development**: Runs app directly for development
+- **Packages**: Creates distributable executables
+- **Cross-Platform**: Windows, macOS, Linux support
+
+```bash
+npm run build:electron:dev         # Runs app directly
+npm run build:electron:appimage:prod  # Linux AppImage
+npm run build:electron:dmg:prod    # macOS DMG
+npm run build:electron:deb:prod    # Linux DEB
+```
+
+### **Build System Features**
+
+- ✅ **Unified Environment Management**: Consistent dev/test/prod modes
+- ✅ **PWA Support**: Progressive Web App functionality across platforms
+- ✅ **Asset Generation**: Automatic icon and splash screen generation
+- ✅ **Docker Integration**: Containerized deployment options
+- ✅ **Performance Optimization**: Build-time and runtime optimizations
+- ✅ **Error Handling**: Comprehensive error reporting and recovery
+- ✅ **Legacy Compatibility**: Backward-compatible script aliases
