Subject: [PATCH] fix: use Call instead of Get+Invoke for fetch to preserve
 this binding

Using namespace.Get("fetch").Invoke(...) detaches the method from its
object, causing "Illegal invocation: function called with incorrect
`this` reference" when used with Cloudflare Service Bindings.

Replace with namespace.Call("fetch", ...), which is equivalent to
namespace.fetch(...) in JavaScript and preserves the correct `this`
reference. This aligns with the existing pattern used in dostub.go.
