Undo Bootstrap

Reverse a bootstrap or retrofit run by walking its BootRecord manifest: restore pre-state files, drop branches that were created, surface anything that couldn't be safely undone. TRIGGER when the user says "undo the bootstrap", "undo nyann setup", "revert nyann setup", "uninstall nyann from this repo", "back out the bootstrap", "undo the retrofit", "I regret running bootstrap", "rip out nyann", "/nyann:undo-bootstrap". ALSO trigger when the user wants to roll back a /nyann:retrofit run that drifted things they didn't expect — retrofit remediation goes through bootstrap.sh, so its boot record is in the same place. DISAMBIGUATION: this is NOT `/nyann:undo` — that one rewinds git commits on a feature branch via `git reset`, completely separate from filesystem mutations bootstrap made. If the user just said "undo my last commit", route to `/nyann:undo` instead. Do NOT trigger on "uninstall the plugin" — that's a Claude Code plugin manager concern, not a per-repo undo. Do NOT trigger on "remove .git" / "delete the repo" — undo-bootstrap explicitly refuses to remove .git/ because doing so destroys all of the user's git state, not just bootstrap's.
