Standard `git log` output (with or without --format). Defaults to the commit-date-author-subject pattern.

JSON array of commits with hash, author, email, date, subject, and body fields. Ready for piping into other tools or visualizations.

One log at a time. For multi-repo analysis, concatenate logs with a repo-name prefix and split after parsing.
