fix: suppress worker-not-found warnings in test environment

The TeamDataWorkerClient logged console.warn when the worker file
was not found, which is expected during tests (no build output).
The test setup treats unexpected warnings as failures.

Downgrade to logger.debug for the "not found" message and remove
the eager warning from resolveWorkerPath().
