fix: use gemini-cli/ as model prefix instead of gc/

Gemini CLI clients use bare model names, not provider-prefixed IDs.
The gc/ alias was opaque — gemini-cli/ is self-documenting. Since
alias now equals provider ID, the dual-prefix duplication logic
naturally skips Gemini CLI (no duplicate gemini-cli/ entries).
