v0.5.0

Added

• /never-stale --off — per-project teardown that is symmetric to setup: it shows
  a plan, confirms, and removes only never-stale's own artifacts (hook script, its
  settings.json hooks, and CLAUDE.md sections still matching the template).
  --off --dry-run previews the removal only. Foreign hooks, user-edited sections,
  and settings.local.json are never touched.
