Reorganizing Python's sys module

Python's sys module has grown into a sprawling junk drawer of 115+ attributes with no clear organization. This thought experiment reimagines sys as a structured package with 9 submodules — from sys.cli to sys.runtime — and explores whether it's technically feasible using module-level __getattr__ and a ModuleType subclass trick. The real takeaway: when your own utils modules get unwieldy, submodules are a practical solution.
