/**
 * LLMProvider — language model abstraction for cortex-engine.
 *
 * Used for cognitive tools that need LLM reasoning:
 * - HyDE query expansion (generate hypothetical passages)
 * - Importance scoring (4-channel: novelty, arousal, reward, attention)
 * - Dream consolidation (memory definition refinement, edge discovery)
 * - Reflective passage generation
 *
 * Implementations: VertexLLMProvider, OllamaLLMProvider, OpenAICompatibleLLMProvider.
