- M3-004: Implement OpenRouterAdapter using openai SDK with custom base URL
(https://openrouter.ai/api/v1). Fetches model catalog on registration,
gracefully degrades when OPENROUTER_API_KEY is absent, streams completions
via OpenAI-compatible API.
- M3-006: Enhance OllamaAdapter with embedding model registration
(nomic-embed-text, mxbai-embed-large) and an embed(text, model?) method
that calls Ollama's /api/embeddings endpoint. listModels() now returns
both completion and embedding models. Prepares for M3-009 EmbeddingService.
