/**
* 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
