fix(dlx): move variable declarations before retry guard to avoid TDZ ReferenceError

The error message in ensurePythonDlx interpolated ${lockFile} and
${pythonDir}, but both were declared after the early-return check,
causing a ReferenceError (temporal dead zone) instead of the intended
InputError when retryCount >= MAX_RETRIES.
