refactor: drop prebuild:packages ceremony from check:local/ci

 - ✅ `pnpm turbo run type-check --filter=@zapengine/frontend` — respects `^build` deps

-The contracts pipeline (`pnpm contracts:check`) bypasses Turbo because `contracts:export` is raw `tsx`, so it keeps the explicit `prebuild:packages` prefix.
+If you hit a stale build anyway, `pnpm --filter @zapengine/types build` (or any specific package) is the targeted fix; `pnpm prebuild:packages` rebuilds all packages but is rarely needed — the `contracts:check` pipeline calls it internally because `contracts:export` is raw `tsx` and bypasses Turbo.
