ci(quick-260623-jwh): wire Vue-leaf gate into vue-matrix.yml (Layer 3)

- new step "Vue-leaf gate — structural guard + strict consumer-surface typecheck"
  runs `pnpm --filter @rozie/vue-typecheck test` (both new gate tests + existing vue-tsc emit tests)
- ordered immediately AFTER `pnpm turbo run build` so every Vue leaf's compiled dist exists before the consumer-surface typecheck resolves it
- ordering check prints OK; YAML valid
