Auto-mode classifier can now retry via a callback instead of always blocking on unavailable results
The function that evaluates the safety classifier's results now accepts a callback. When the server's result was skipped or the classifier's response type isn't recognized, it now invokes that callback instead of automatically falling back to the "blocking for safety" response.
Previously, any skipped or unrecognized classifier result meant the action was blocked outright. Now there's a path to retry or handle that case differently, which can reduce unnecessary blocking when the classifier result is simply missing or malformed rather than genuinely unsafe.
