- Strip additionalProperties and $schema from tool parameter schemas
(Gemini API rejects these unsupported JSON Schema fields)
- Add thoughtSignature to functionCall parts for multi-turn tool calling
(Gemini 3 models require thought signatures on function call history)
- Ensure functionResponse.response is always a JSON object, never an
array or primitive (wrap non-objects in {"result": ...})
- Resolve tool names from tool_call_id or positional index when the
tool message doesn't carry a name field
- Add functionCall parsing in streaming responses (emitGeminiChunk)
to properly relay tool calls via SSE
- Add error logging for Gemini stream failures with request body dump
- Add unit tests for schema cleaning and streaming tool call emission
