build: unify vendor pipeline, externalize head JS, switch docs to pnpm

- Remove modules/blox-tailwind/vite.config.js; use root Vite vendor task
- Vendor alpinejs and markmap; add vendor-libs.js stub
- Replace inline head scripts with CSP-friendly hb-head.js; add font preload + fingerprint
- Update scripts/docs to pnpm; remove unused @tailwindcss/vite
