Gemini claims to be Claude

...so I thought the proxy wasn't working but after double checking it seems to work fine, just Gemini believe it is Claude.

Maybe you should hardcode patch(es) on the segment of the system prompt that says: "You are Claude Code, Anthropic's official CLI for Claude. You are an interactive CLI tool that helps users with software engineering tasks. [...] You are powered by the model named Opus 4. The exact model ID is claude-opus-4-20250514."

PS: the DEBUG log level leaks the complete API key, you probably want to fix that quickly or warn users in the README

Thanks for your work!
