feat: major retrieval + ingestion + graph intelligence overhaul

- 5-signal retrieval: BM25 + Graph BFS + Recency + HNSW Vector + Entity Boost
- Query planner with intent-aware routing (Why/How/When/What)
- MMR diversity reranking, query expansion (50+ coding synonyms)
- Bloom filter for O(1) negative lookups
- HNSW vector index (pure Go, O(log n) ANN search)
- Spread-attenuated entity boost (Mem0 v3 technique)
- Query cache (LRU, auto-invalidate on writes)
- GraphRAG community detection + hierarchical memory (RAPTOR)
- Memory sparsification (merge duplicates, compress, prune orphans)
- HMAC-SHA256 integrity verification
- Git learning (yaad learn, yaad suggest)
- Smart ingestion (conversation, markdown, code, CLAUDE.md, .cursorrules)
- Stack detection, session handoff, temporal filtering
- PageRank importance scoring, shortest path, orphan detection
- Context window optimizer, feedback signals, contextual scoring
- Quiz, export-html, templates, health checks, audit log, rate limiter
- One-command auto-setup with agent detection
- Python + TypeScript SDKs, D3.js dashboard
- 57 CLI commands, 28 MCP tools, 42 REST endpoints
