On macOS, WKWebView doesn't expose Chrome DevTools Protocol (CDP), which means execute_js and screenshot tools don't work. This commit: - Adds comprehensive documentation in README about the tauri-plugin-native-webview solution for macOS WebView debugging - Updates error messages in debug.rs to guide users to the plugin when CDP fails - Adds docstring hints in window.rs about using the plugin for hidden screenshots - Adds suggest_native_plugin() helper for future auto-detection The plugin provides: - Native WKWebView screenshots (works when window is hidden) - JS evaluation with return values via IPC - Debug info via Tauri APIs Users can use call_ipc_command with plugin commands: - plugin:native-webview|snapshot - plugin:native-webview|eval_js - plugin:native-webview|debug_info Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
