One-shot bash migration block for repos onboarded before this layout:
creates .claude/{tasks,memory,audits}, moves tasks/*.md + AUDIT_* +
orphan root audits (SEO/GEO/HARDEN/VALIDATE/BUGS-FOUND) to the new
homes, seeds memory registries from templates, patches .gitignore to
un-ignore shared dirs, and ships a post-migration sanity check.
Uses mv throughout (no rm) so the migration stays reversible via
git checkout . until the commit.
