Phase 5 (Runtime) Test Runner for Mojo Compiler
================================================
This runner executes Phase 5 tests using the Mojo compiler implementation.
It chains Phases 1-4 and executes Phase 5 runtime operations:
1. Load snake.mojo source
2. Run Phases 1-4 (Frontend, Semantic, IR, Codegen)
3. Execute Phase 5 (Runtime):
- FFI binding for SDL3
- Memory allocation and initialization
- Execution with timeout
4. Capture and report results
Reports:
- FFI symbols linked
- Memory allocated
- Execution status
- Exit code
