Deprecated `enableHandshake` option and `req.auth` object-access removed from `@clerk/express`

enableHandshake option removed

The enableHandshake option had no effect and has been removed from clerkMiddleware.

- app.use(clerkMiddleware({ enableHandshake: false }));
+ app.use(clerkMiddleware());

req.auth object-access removed

Accessing req.auth as a plain object (legacy clerk-sdk-node style) is no longer supported. Use getAuth() instead.

- const { userId } = req.auth;
+ const { userId } = getAuth(req);
