Feature: prevent auto-update to unsupported versions

[Nucs]

Hey, I was wondering if it would be possible to maintain auto-update for Claude Code enabled but not allow it to go to a version beyond tweakcc's current support.
This will allow the users to maintain latest features automatically but also never losing tweakcc (for cases where you are reliant on the system prompts modifications).

Thanks

That's a cool idea, I'll see about that. It should be as simple as patching the auto update checker to check for the existence of https://github.com/Piebald-AI/tweakcc/blob/main/data/prompts/prompts-<version>.json and then either stop or continue with the auto updating.
