Author Contributions

This does the grunt work of figuring out which files an author actually contributed to on a branch, including code that survives through renames. It's designed to run as a subagent because it shells out to a dozen git commands, builds a rename chain by walking every commit on the branch, then cross-references author commits against the final merge diff. The procedure is opinionated: it uses Python instead of shell loops to avoid zsh comment breakage, insists on exact author matching via git log output, and only reports files that will actually land in the merge. Useful before code review when you need to audit contributions or answer "what did this person touch" without manually grepping through history.
