"""Phase 2 (Semantic Analysis) execution test for the Mojo compiler.
This test runner:
1. Loads the Mojo compiler's Phase 1 (Frontend) output
2. Executes Phase 2 (Semantic Analysis)
3. Collects symbol table metrics
4. Validates type safety
5. Reports ownership violations and type errors
6. Documents comprehensive test results
