Pull request overview

This PR refactors setupmeta.run_program() and related SCM execution paths to use a structured RunResult (via subprocess.run()), while removing several legacy features (old setuptools hook alias, deprecated commands, and pygradle-style versioning) and updating tests/scenario fixtures accordingly.

Changes:

• Refactors program execution and git SCM interactions to consistently return/consume RunResult objects.
• Removes legacy commands (entrypoints, cleanall), old setuptools v50 register hook alias, and pygradle versioning support.
• Updates tests, scenario outputs, documentation, and CI workflows to match the new behavior.
