pyjwt is missing from Mac credential-helper executable

[rlvoyer]

The error:

  code-dist % ~/claude-code-with-bedrock/credential-process
  Traceback (most recent call last):
    File "cognito_auth/__main__.py", line 17, in <module>
  ModuleNotFoundError: No module named 'jwt'
  [PYI-14351:ERROR] Failed to execute script '__main__' due to unhandled exception!

The problem:

PyInstaller doesn't include the pyjwt module which brings jwt in as a transitive dependency.
