What changed?

This PR makes a TypeScript System Nexus operation that returns a resource build the resource from the answer.

The System Nexus branch of the TypeScript operation function returned result as <Resource>. The answer is the resource's wire message, such as StartWorkflowExecutionResponse, not the resource. Now the branch builds the resource from its bindings, as the endpoint branch does: return new StartedWorkflow(request.namespace, request.workflowId, result.runId ?? undefined).

Why?

The cast compiled, but at run time the caller got a plain message with no resource methods and no resource fields. A call to a resource method on it failed.

How did you test it?

tests/generate_typescript.rs generates the start-workflow sample with System Nexus on, and checks that startWorkflow builds a StartedWorkflow. The test fails on main.

cargo test --features advanced passes. cargo build-examples --lang typescript gives no diff. In advanced/samples/typescript, npm run typecheck and npm test pass.

Came from fork PR #45.
