red-skills-dev: no RedSkills dev runtime found.

Expected one of:
- an installed dev plugin under ~/.codex/plugins/cache/red-skills/dev/*
- an installed dev plugin under ~/.claude/plugins/cache/red-skills/dev/*

The dev runtime bundle was deleted by ADR 0147; any leftover
~/.cache/red-skills/bundles/dev-*.bundle.min.mjs is inert and safe to remove.

Fallback:
  npx -y -p @reddb-io/red-skills@<version> red-skills-dev "$@"

Run /red-setup in a repo with plugins.dev.enabled: true, then restart the
agent session so the plugin SessionStart hook can warm the runtime cache, or use
the npm direct-run fallback above for a fresh machine.
