feat: add MiniMax as LLM provider

[octo-patch]

Summary

Add MiniMax AI as a first-class LLM provider in SmythOS SRE, using the existing OpenAI-compatible connector pattern (same approach as DeepSeek and TogetherAI).

• Register MiniMax in BuiltinLLMProviders enum and wire it to OpenAIConnector
• Add 4 MiniMax models: M2.7 (1M context), M2.7-highspeed, M2.5 (204K context), M2.5-highspeed
• Add 10 unit tests + 5 integration tests (all passing)
• Update README to list MiniMax as a supported LLM connector

Why MiniMax?

MiniMax provides OpenAI-compatible chat completion APIs with competitive models:

• MiniMax-M2.7: Latest model with 1M token context window
• MiniMax-M2.5: 204K context with highspeed variant for lower latency

Since the API is fully OpenAI-compatible, no new SDK dependency or custom connector is needed — MiniMax reuses the existing OpenAIConnector with baseURL: 'https://api.minimax.io/v1'.

Usage

// SDK factory
const llm = LLM.MiniMax('MiniMax-M2.7', { temperature: 0.7 });
const response = await llm.prompt('Hello!');

// Model factory
const model = Model.MiniMax('MiniMax-M2.7');

@octo-patch Hey, thanks so much for this contribution! Really appreciate you taking the time to add MiniMax as a provider.

We'll run through our own testing on our end to make sure everything integrates cleanly, and then we'll get this merged. Thanks again, great first contribution to the project!
