feat(weave): TS SDK: allows call handle to be returned

[chance-wnb]

Description

Adds a new invoke method to ops that returns both the result and a Call object, allowing users to update call metadata after execution. The Call object provides a setDisplayName method to change the display name of a call even after it has completed.

Testing

Tested by creating ops, calling them with the new invoke method, and verifying that the returned Call object can be used to update the display name both during and after execution.

Some unit tests scenarios are authored as well.
