PR Overview

This PR addresses an asynchronous delay in populating draft issues when copying a project by implementing a polling mechanism that waits for the draft issues to fully populate before proceeding with template interpolation.

• Introduces a wait loop in copy-project.ts to poll for draft issue completion using the new getProject API.
• Updates tests to mock the new getProject function appropriately.
