Ignore .claude/ wholesale instead of file by file

The rig files were listed individually, so each new one started out
tracked: cite-harness.html and worktrees/ were both sitting untracked and
unignored, one `git add .` from being committed. Nothing under .claude/
has ever belonged in the repo (git ls-files confirms zero tracked), so
ignore the directory and note how to unignore a file if that changes.
