git-history-clean-skill

This skill should be used when preparing a git repository for public release by stripping dev tooling artifacts (e.g. .beads/, .ralph-tui/, editor configs, CI caches) from entire git history. Also use when the user wants to remove tracked files from all commits, not just the working tree. Triggers on phrases like "clean history", "strip files from history", "prepare repo for publishing", or "remove X from all commits".
