chore(deps): move git2 ownership into tinycortex - #5544

Reviewed 4 files; 0 findings. Code retrieval was unavailable (model: openrouter embeddings returned 402 Payment Required: {"error":{"message":"Insufficient credits. Add more using https://openrouter.ai/settings/credits","code":402,"metadata":{"limit_source":"openrouter_credits","remedy_hint":"Add credits at https://openrouter.ai/settings/credits, or lower max_tokens / prompt size to fit your remaining balance."}}}), so this review saw the diff alone.

No findings.
