/**
 * A generic OpenAI-compatible Chat Completions client (`/v1/chat/completions`, choices[]) — wire
 * types and parsing shared via ChatCompletionsProvider. Backs two CLI-only protocols (see
 * runtime/cli/src/serve/server.ts `resolveLocalProvider`):
 *   - `ollama`        — zero-config preset: keyless, base URL OLLAMA_HOST / http://localhost:11434.
 *   - `openai-compat` — generic: base URL TB_AI_BASE_URL, optional key TB_AI_API_KEY (LM Studio,
 *                       vLLM, a self-hosted endpoint, a keyed proxy, a cloud OpenAI-compat vendor).
 * Auth is optional — `buildHeaders` sends `Bearer <key>` only when a key is present.
 *
 * It's its own class (not OpenAIProvider) because the `openai` protocol targets the Responses API
 * (`/v1/responses`), which these endpoints don't implement. Ollama's native `/api/chat` (NDJSON,
 * first-class `message.thinking`, `num_ctx`/`think` options) is out of scope for tb.ai — reach it
 * via a server.ts export. See runtime-specs/TB-Custom-Providers.md.
