/**
 * RuVector-Enhanced Agent Booster v2
 *
 * Full upgrade with all RuVector capabilities:
 * - Semantic fuzzy matching (cosine similarity on embeddings)
 * - ONNX embeddings for semantic code understanding
 * - Parallel batch apply for multi-file edits
 * - Context-aware prefetch (predict likely edits)
 * - Error pattern learning (learn what NOT to do)
 * - TensorCompress for 10x more patterns in memory
 * - SONA continual learning with EWC++
 * - GNN differentiable search
 *
 * Performance targets:
 * - Exact match: 0ms
 * - Fuzzy match: 1-5ms
 * - Cache miss: 650ms (agent-booster)
 * - Pattern capacity: 100,000+ with compression
