list_versions

List the version history (git commits) for a Bridge Town model. When path is provided (e.g. model/revenue.py, README.md, data/seed.csv), only commits that touched that file are shown; omit path to list model-wide history. Each version includes the commit SHA, human-readable commit message (derived from the natural-language prompt used to create or update the file), author name, and date.
