/**
 * Ollama Provider — direct HTTP, no AI SDK.
 *
 * Wraps a local (or remote/Cloud) Ollama server via its OpenAI-compatible
 * `/v1` API. All request / stream / multi-step tool-loop orchestration lives
 * in `OpenAIChatCompletionsProvider`; this class declares configuration plus
 * the Ollama-specific behaviour:
 *
 *   1. `/v1` base-URL normalization (accepts a bare `OLLAMA_BASE_URL` host).
 *   2. No-auth-by-default with an optional `OLLAMA_API_KEY` for Ollama Cloud.
 *   3. Configurable per-model tool gating via `OLLAMA_TOOL_CAPABLE_MODELS` /
 *      `modelConfig` (`supportsTools`).
 *   4. Elevated request timeout for slow large local models (5-minute base
 *      default, overridable via `OLLAMA_TIMEOUT`).
 *   5. Native `/v1/embeddings` (`embed` / `embedMany`).
 *   6. Rich, actionable error mapping (`ollama serve` / `ollama pull` hints).
 *
 * Model discovery uses the base's `/v1/models` probe (Ollama supports it).
 *
 * @see https://docs.ollama.com/api/openai-compatibility
