Subject: [PATCH] provider: add Mixlayer

Mixlayer (https://mixlayer.com) is an OpenAI-compatible inference platform
for open models, with its serving stack built from scratch by core
contributors to Candle. API base: https://models.mixlayer.ai/v1.

Adds the provider under src/providers/mixlayer/ following the open-ai-base
pattern (like Cerebras), registered in globals.ts and providers/index.ts.
Chat completions with streaming and tool calling; reasoning_effort is
forwarded for thinking-capable models.
