chore(tooling): port upstream infra/tooling audit fixes

Reconciles the upstream audit-fix PR's infra changes onto the Veect
control-plane fork (kept-file portions only; deleted demo features
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; fix the
  work-tree fixtures to mirror the docs/work/epics/ layout
- 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)
