feat(ios): create iOS test app structure and synchronization documentation

Created standalone iOS test app structure matching android-test-app:
- Added ios-test-app directory with README, setup guide, and build scripts
- Created comprehensive iOS synchronization status documentation
- Documented API method gaps between Android (52) and iOS (9 methods)
- Added iOS setup guide for Vue 3 test app

New files:
- test-apps/ios-test-app/ - Standalone iOS test app structure
- docs/IOS_SYNC_STATUS.md - Detailed API comparison and status tracking
- docs/IOS_SYNC_SUMMARY.md - Summary of iOS synchronization work
- test-apps/daily-notification-test/docs/IOS_SETUP.md - Vue app iOS setup

iOS test environments are now ready for setup. Test apps need Xcode project
generation via Capacitor CLI or copying from ios/App.

Next steps: Generate Xcode projects and implement missing API methods.

+# iOS Test App for DailyNotification Plugin
+
+**Author**: Matthew Raymer  
+**Date**: 2025-11-04  
+**Version**: 1.0.0
+
+## Overview
+
+Standalone iOS test application for the DailyNotification Capacitor plugin. This app provides an interactive testing interface for all plugin features, similar to the Android test app (`android-test-app`).
+

+```
+
+## Prerequisites
+
+- Xcode 14.0 or later
+- CocoaPods (`gem install cocoapods`)
+- Node.js (for Capacitor CLI)
+- iOS 13.0+ deployment target
+
+## Setup
+
+### 1. Install CocoaPods Dependencies
+
+```bash
+cd test-apps/ios-test-app/App
+pod install
+```
+
+### 2. Build Plugin First
+
+```bash
+# From project root
+./scripts/build-native.sh --platform ios
+```
+
+### 3. Open in Xcode
+
+```bash
+cd test-apps/ios-test-app/App
+open App.xcworkspace
+```
+
+## Building
+
+### Using Xcode
+
+1. Open `App.xcworkspace` in Xcode
+2. Select target device/simulator
+3. Build and run (⌘R)
+
+### Using Command Line
+
+```bash
+# Build for simulator
+xcodebuild -workspace App.xcworkspace \
+    -scheme App \
+    -configuration Debug \
+    -sdk iphonesimulator \
+    -destination 'platform=iOS Simulator,name=iPhone 15 Pro' \
+    clean build
+
+# Install on simulator
+APP_PATH=$(find build -name "*.app" -type d | head -1)
+xcrun simctl install booted "$APP_PATH"
+xcrun simctl launch booted com.timesafari.dailynotification
+```
+
+### Using Build Script
+
+```bash
+cd test-apps/ios-test-app
+./scripts/build-and-deploy.sh
+```
+
+## Plugin Integration
+
+The plugin is integrated via CocoaPods:
+
+```ruby
+# Podfile
+pod 'DailyNotificationPlugin', :path => '../../../ios'
+```
+
+## Features
+
+- Interactive plugin testing interface
+- Plugin diagnostics and status checking
+- Notification scheduling and management
+- Permission testing and management
+- Comprehensive logging and debugging
+
+## Testing
+
+The test interface is available at `App/App/public/index.html` and provides buttons for:
+
+- Plugin availability testing
+- Configuration
+- Status checking
+- Notification scheduling
+- Permission management
+- Channel management
+
+## Troubleshooting
+
+### Plugin Not Found
+
+Ensure the plugin is built first:
+```bash
+./scripts/build-native.sh --platform ios
+```
+
+### CocoaPods Issues
+
+```bash
+cd test-apps/ios-test-app/App
+pod deintegrate
+pod install
+```
+
+### Build Errors
+
+1. Clean build folder in Xcode (⌘⇧K)
+2. Delete derived data
+3. Rebuild
