[BUG] Safety classifier too sensitive - switches to Opus 4.8 for harmless commands like /feedback

What's Wrong?

Fable 5's safety classifier is too aggressive. Even typing harmless commands like /feedback triggers an automatic switch to Opus 4.8, wasting tokens. This happens even with autoSwitchModels: false in settings.json.

What Should Happen?

Fable 5 should handle simple commands without flagging them as unsafe. The safety threshold should be more reasonable.
