/**
 * AI SDK provider factory for LM Studio.
 *
 * LM Studio's HTTP API is OpenAI-compatible, so we use `@ai-sdk/openai-compatible`
 * (not `@ai-sdk/openai`) — that adapter is purpose-built for OpenAI-shaped servers
 * that don't implement the full OpenAI feature surface (e.g. assistants, image
 * generation), which describes LM Studio exactly.
 *
 * Why a thin wrapper: the AI SDK exposes `createOpenAICompatible` with a `name`,
 * `baseURL`, and optional `apiKey`. Centralizing the factory means tests can mock
 * one entry point, and the auto-detect + init paths share the same client construction.
