- Introduced a `ConvertGeminiRequestToGemini` function to normalize Gemini v1beta requests by ensuring valid or default roles.
- Added passthrough response handlers for both streamed and non-streamed Gemini responses.
- Registered translators for Gemini-to-Gemini traffic in the initialization process.
- Updated `gemini-cli` request normalization to align with the new Gemini translator logic.
- Comment out verbose routing logs in the API server to reduce noise.
- Remove the `tools` field from Qwen client requests when it is an empty array.
- Add guards in Claude, Codex, Gemini‑CLI, and Gemini translators to skip tool conversion when the `tools` array is empty, preventing unnecessary payload modifications.
