test(node): e2e tests for expressjs

[dinwwwh]

Express.js is now covered by the shared adapter test matrix, so @standardserver/node is verified against a real express app rather than only bare node:http. Two variants run: a plain app, and one with express.json() registered the way an ordinary project does.

Coverage

Both variants run the full data-transfer and signal-and-cancel suites — url/method/header/status round-trips, every body kind (json, blob, file, form-data, event-stream, octet-stream), parallel-chunk streaming timing, abort signals, and stream cancellation.

The req.body short-circuit in the node adapter is now exercised end to end: with express.json() in front, JSON bodies arrive pre-parsed and every other content type still reaches the adapter as an untouched stream. Streaming, abort, and cancellation behave identically with and without the parser.

req.originalUrl handling is also covered for the first time by a real express request.

Compatibility note

express.json() must be registered with strict: false. Its default rejects any top-level JSON value that isn't an object or array — "a string", null, 1 — with a 400 before the adapter ever runs, and those are valid standard-server bodies. The test harness documents this inline.

Testing

966 tests pass. Lint and type check are clean.
