"""End-to-end integration tests for Vue parser Phase 2 features.
This test suite comprehensively tests all Phase 2 features working together:
- Phase 2.1: Tree-sitter section extraction
- Phase 2.2: Template directive parsing
- Phase 2.3: Cross-reference analysis
Tests use realistic Vue component examples and verify the complete parsing pipeline.
