normalizeModelName reduces gpt-5.2-chat-latest to gpt-52-chat-latest,
which matches the gpt-52 prefix and gets reasoning_effort='none'.
But chat-latest models don't support reasoning_effort, causing
HTTP 400.
Fix: check for 'chat-latest' before applying reasoning_effort patches.
Fixes#563
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
