portable_python: Self-contained Python distribution for Linux

A new portable Python distribution allows developers to run Python applications on any Linux system without installing system dependencies or managing complex environments. The tool uses a clever launcher that dynamically loads Python libraries at runtime, enabling full support for popular packages like NumPy and pandas while maintaining complete portability across different Linux distributions. Weighing just 38MB compressed, it includes pre-installed pip and creates instant environments using hardlinks rather than copying files.
