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)
