/**
|
|
* 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
