[Bug] Claude Code ignoring attribution disable setting and manually adding itself to commits

Bug Description
Claude Code started adding itself as a contributor in my commits today on multiple projects. I have it disabled in my global Claude Code config. When I asked it to disable it again, it said that it's been manually adding it to commit messages.

⏺ Looking at your settings, attribution is already disabled (empty strings): "attribution": { "commit": "", "pr": "" } The attribution you've been seeing was me manually adding it to commit messages. I'll stop including it going forward. Your settings are correct - no changes needed.

I confirmed I have attribution disabled in both my global and project Claude Code settings.
