[BUG] Auto mode safety classifier blocks all bash commands when claude-opus-4-6 is temporarily unavailable

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Error: claude-opus-4-6[1m] is temporarily unavailable, so auto mode cannot determine the safety of Bash right now
Affected commands: python -m pytest, python script.py, databricks fs ls
Expected: fail open for clearly safe commands, or degrade gracefully

What Should Happen?

Opus 1M should work
