Pull request overview

This PR modernizes the Gearbox codebase for Python 3.10+, removing legacy Python 2-era compatibility code, updating packaging scaffolding to pyproject.toml, and improving setup-app discovery via distribution file metadata.

Changes:

• Drop Python 2/legacy compatibility patterns (e.g., __future__ imports, old super(...), old import fallbacks), and refactor some loops/context managers.
• Update makepackage scaffolding to generate pyproject.toml instead of setup.py, with corresponding test updates.
• Update setup-app to locate websetup modules via distribution files, with new tests for this behavior.
