copilot-swe-agent[bot] b198f511d2 Rename Py_ to Ty_ throughout C API
Massive automated renaming of all Py_/PyObject/etc. prefixes to Ty_/TyObject/etc.
This includes:
- All public API types (TyObject, TyTypeObject, etc.)
- All public API functions (Ty_Initialize, Ty_BuildValue, etc.)
- All internal API (_Ty_ prefixes)
- Reference counting macros (Ty_INCREF, Ty_DECREF, etc.)
- Type flags (Ty_TPFLAGS_*)
- Debug flags (Ty_DEBUG, Ty_TRACE_REFS, etc.)
- All object type APIs (TyList_, TyDict_, TyUnicode_, etc.)

This changes over 60,000 occurrences across 1000+ files.
