Phase 1: extract.js — tree-sitter AST parser (TS/JS/Python/Go/Java/Bash) + config parsers (YAML/HCL)
Phase 2: graph.js — in-memory directed graph store with build/query/diff CLI
Phase 3: namespace.js — cross-repo namespace registry with 3-tier resolution
Phase 4: semantic-diff.js — categorized diffs with impact scoring (0-100)
Phase 5: pipeline.js — batch extraction, incremental diffing, benchmarking

Benchmark: 4,325 files, 21,646 nodes, 133,979 edges in 67s (15ms/file)
