/**
 * DeepSeek Provider — direct HTTP, no AI SDK.
 *
 * OpenAI-compatible chat completions at api.deepseek.com (deepseek-chat /
 * deepseek-reasoner). All request/stream/tool-loop orchestration lives in
 * `OpenAIChatCompletionsProvider`; this class declares configuration and
 * provider-specific quirks:
 *
 *   1. Structured-output downgrade — DeepSeek rejects `response_format:
 *      { type: "json_schema" }` ("This response_format type is unavailable
 *      now"), so `adjustResponseFormat` downgrades it to `json_object` —
 *      matching the `supportsStructuredOutputs: false` behaviour of the
 *      `@ai-sdk/openai-compatible` path this migration replaced. The base
 *      client injects the literal "json" word the API requires for that mode.
 *
 *   2. Reasoning support — `reasoning_content` (deepseek-reasoner / R1) is
 *      surfaced automatically by the native base client: streamed deltas
 *      arrive as `{ content: "", reasoning }` chunks and the non-streaming
 *      result carries `result.reasoning`. The opt-in `thinking` request
 *      param (non-reasoner chat models) still needs thinking-signal plumbing
 *      and is tracked as a follow-up. All other behavior is preserved.
 *
 * @see https://api-docs.deepseek.com
