test(integration): parallelize beforeAll builds and tighten d.bark() assertions (#1428)

- Run both WASM and native buildGraph calls concurrently via Promise.all;
  fixtures are already written to separate dirs before either build starts
- Pin d.bark() assertions to src === 'proto.js' (the file-level scope node)
  so the check no longer matches any edge that targets Dog.bark
