fix(macOS): add comprehensive WebView debugging and navigation delegates

WINDOWS FIX (UwbWebView.cs):
- Corrected UniTask.WhenAny return type handling
- Fixed: error CS0019 'bool' vs 'int' comparison
- Changed to: int winIndex = await UniTask.WhenAny(...)

MACOS IMPROVEMENTS (ImmutableWebView.mm):
1. Enable developer extras and Safari debugging (always on, not just #ifdef)
   - Allows remote debugging of WebView content

2. Add didFinishNavigation delegate
   - Logs successful page loads
   - Tests JavaScript execution immediately after load
   - Helps diagnose if JS is running

3. Improve error delegates (didFailNavigation, didFailProvisionalNavigation)
   - Add detailed NSLog with error code
   - Helps diagnose navigation failures

4. Recompile ImmutableWebView.bundle with all changes

GOAL: Get detailed logs to understand why JavaScript is not executing in CI/CD
