Add MiniMax (M2.5 / M2.5-highspeed) as a tested model provider:
- Add model-specific patch in utils.ts: clamp temperature to (0, 1]
since MiniMax API rejects temperature=0, and remove unsupported
parallel_tool_calls parameter
- Add MiniMax to the tested models list on the Models documentation page
- Add MiniMax configuration example alongside existing providers
