Add evaluation framework and fix call graph extraction
- Add evaluation test suite with TypeScript and Python fixtures - Fix MCP server to defer CodeGraph init until rootUri received - Fix call edge extraction by calling resolveReferences() after indexAll/sync - Fix glob matching for root-level files (e.g., **/*.py now matches auth.py) - Fix duplicate node extraction for methods inside classes - Update context tests to use buildContext for semantic search + graph traversal - Export unused formatter functions to fix build Evaluation results: - TypeScript: 96% precision, 79% recall, 85% F1 - Python: 99% precision, 80% recall, 85% F1 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
