hugocasaandClaude Opus 4.6 1503bf948e fix: stop_after_if with empty error_message prevents flow from stopping (#8464)
* fix: stop_after_if with empty error_message no longer prevents flow from stopping

When skip_if_stopped=true and error_message="" were both set, the flow
would continue executing instead of stopping because the empty string
was converted to a default error message, which triggered the error
handler path. Now skip_if_stopped takes precedence and the two options
are treated as mutually exclusive in both backend and frontend.
