Replace deprecated Python C API calls with modern PyConfig-based initialization:
- PySys_SetArgvEx() -> PyConfig.argv (deprecated since 3.11)
- Py_InspectFlag -> PyConfig.inspect (deprecated since 3.12)
Fix critical memory safety bugs discovered during migration:
- PyColor::from_arg() and PyVector::from_arg() now return new references
instead of borrowed references, preventing use-after-free when callers
call Py_DECREF on the result
- GameEngine::testTimers() now holds a local shared_ptr copy during
callback execution, preventing use-after-free when timer callbacks
call delTimer() on themselves
Fix double script execution bug with --exec flag:
- Scripts were running twice because GameEngine constructor executed them,
then main.cpp deleted and recreated the engine
- Now reuses existing engine and just sets auto_exit_after_exec flag
Update test syntax to use keyword arguments for Frame/Caption constructors.
Test results: 127/130 passing (97.7%)
