chore(root): Add .smart_git_commit.py.old

This commit adds a backup file (.smart_git_commit.py.old) and a new directory 'smart_git_commit' to the project's root.  This likely indicates a planned refactoring or significant change related to git commit management or automation within the project.  The purpose of the changes is not entirely clear from this commit alone, but it appears to be the beginning of a new feature/implementation.
Affected files:
- + .smart_git_commit.py.old
- + smart_git_commit/
