//! # Brain Hippocampus
//!
//! Memory engine providing:
//! - Episodic memory (conversation storage with decay)
//! - Semantic memory (fact storage with vector embeddings)
//! - Procedural memory (learned workflows)
//! - Importance scoring (keyword-based, no LLM)
//! - Embedding pipeline (Ollama / OpenAI-compatible)
//! - Hybrid search (vector ANN + BM25 FTS5 + RRF fusion)
//! - Memory consolidation (sleep cycle)
