chore(docs-site): add dev shortcut and fix hero heading clipping

- Add `pnpm docs` script that frees port 3000 then runs the docs-site
  dev server, so the docs preview is one command away.
- Bump hero heading line-height to 1.2 and add 0.15em bottom padding
  so the gradient text-clip no longer cuts off descenders.
- Sync auto-generated next-env.d.ts to the current Next types path.
