Upgrade from wookstar-claude-plugins 6.x to 7.0.0.

Updates the plugins you keep, uninstalls the retired ones and installs the
official replacement for each, fills in the settings that credential plugins now ask for (reusing your
old shell variables where it finds them), and lists suggestions for plugins
that lost components. See MIGRATION.md.

Usage: upgrade-v7.sh [--dry-run] [--no-install]
  --dry-run     print what would happen without changing anything
  --no-install  update kept plugins and uninstall retired ones; install and
                configure nothing

Piped from curl, pass options after `bash -s --`:
  curl -fsSL <url>/upgrade-v7.sh | bash -s -- --dry-run
