Code Review

This pull request significantly enhances the WebView widget by introducing native frontend serving capabilities and a transparent fetch proxy to bypass CORS. Key additions include serveFromDisk for serving files via custom URI schemes or virtual hosts, serveVite for seamless development and production workflows, and enableFetchProxy which routes JavaScript fetch calls through PHP. The C++ helper binary was updated to support these features across all platforms and now includes a UI delegate for macOS to handle JavaScript dialogs. Review feedback identified a potential buffer truncation issue in the C++ path construction and logic errors in the PHP streamRequest fallback regarding redirect handling and status code reporting.

The streamRequest method has two significant issues: it defaults to status 200 even if the request fails (e.g., network error), and it only parses the status code from the first header. If a redirect occurs, it will return the redirect status (like 301) instead of the final response status. Additionally, it mixes headers from all responses in the redirect chain.

        $res = @file_get_contents($url, false, stream_context_create(['http' => $opts]));
        $resBody = $res === false ? '' : $res;
        $status = $res === false ? 500 : 200;
        $resHeaders = [];

        // $http_response_header is set by file_get_contents in the local scope
        $responseHeaders = $http_response_header ?? [];
        foreach ($responseHeaders as $h) {
            if (preg_match('/HTTP\/[\d.]+\s+(\d+)/', $h, $m)) {
                $status = (int)$m[1];
            } elseif (str_contains($h, ':')) {
                [$k, $v] = explode(':', $h, 2);
                $resHeaders[trim($k)] = trim($v);
            }
        }

The filepath buffer size might be insufficient. Since g_serve_dir can be up to 4096 bytes and the requested path can also be long, truncation could occur. This would cause realpath to fail or return an incorrect path, potentially breaking asset loading for deep directory structures.
