Bug Report

Environment:

• SDK: Node.js/TypeScript
• Node version: 22.x
• SDK version: 0.1.0

Steps to reproduce:

1. Initialize the copilot-sdk client
2. Call session.create({}) with empty options object
3. Observe that the return value is undefined instead of a session object

Expected behavior: session.create should return a session object.

Actual behavior: Returns undefined.
