Lens Core - High-Performance Code Search Engine

A production-ready code search engine with:

• LSP-first architecture with real language server integration
• Zero-copy fused pipeline for ≤150ms p95 latency
• Bounded BFS for def/ref/type/impl traversal
• SLA-bounded metrics: Success@10, nDCG@10, SLA-Recall@50
• Built-in benchmarking and fraud-resistant attestation
