fix: websocket check to prevent runtime conflict on network framework

[NathanWalker]

Browser-compatible WebSocket implementation in the createInspectorSocket function to prevent runtime errors when running in environments where a non-browser global WebSocket is present, such as NativeScript on iOS. The main change is the introduction of a stricter check for a browser-style WebSocket before attempting to instantiate it.

WebSocket environment detection improvements:

• Replaced the previous typeof WebSocket === "function" check with a new isBrowserWebSocket function in index.ts to ensure the global WebSocket is compatible with browser APIs before using it. This prevents instantiation errors with native classes that are not true WebSocket polyfills.
• Added the isBrowserWebSocket helper function, which checks for browser-style readyState constants (CONNECTING, OPEN) and the presence of send and close methods on the prototype, ensuring only real browser WebSocket polyfills are used.
