Ports the kept-file portions of the upstream infra audit-fix subset onto
the clean-slate template branch (auth-only shape; workspaces feature never
existed here, so its package.json edit is skipped):
- resolve the root playwright config in pnpm test:visual (S8)
- prune dead VERCEL_ENV from turbo.json globalEnv (S9)
- drop the duplicate chromium install in the storybook CI job (S10)
- wire scripts/**/*.test.mjs under a dedicated vitest runner
(vitest.scripts.config.mjs + pnpm test:scripts + CI validate step);
convert node:test imports to vitest keeping node:assert
- ignore *.tsbuildinfo repo-wide and untrack the committed build state
- align every @trpc/* range on ^11.18.0 so the workspace resolves to a
single version (peer-warning-free install)
