[ENHANCEMENT] Request: Implement Minimax Provider in Anthropic SDK

[kavehsfv]

Problem (one or two sentences)

Hi Roo Code Community,

Could you please implement a Minimax provider in the Anthropic SDK, rather than the OpenAI one? The Minimax company has clearly stated that their model accuracy is much higher when integrated with the Anthropic SDK, as detailed in this article: Link

For reference, a Minimax provider has already been implemented in Cline with Anthropic SDK here: Link

I'm exploring a potential fix for implementing the Minimax provider using the Anthropic SDK as requested. I'll open a PR to share progress on this enhancement.

I've successfully implemented the requested enhancement and opened PR #9084 with the changes: #9084

The implementation migrates the Minimax provider from OpenAI SDK to Anthropic SDK as requested, following the patterns established in the existing Anthropic provider. All tests are passing and CI checks have completed successfully.

Key changes:

• Replaced OpenAI SDK with Anthropic SDK for Minimax provider
• Added support for Anthropic-specific features (prompt caching, reasoning blocks, usage tracking)
• Updated all tests to mock Anthropic SDK
• Maintained backward compatibility with existing configurations

Feedback and review are welcome!
