feat: add MiniMax model support with temperature clamping

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
