Step 2 replaced uuid by crypto.randomUUID() at three call sites (AlexaStatusMessage, AlexaErrorResponse,
Device.sendSceneResponse) and only the first was asserted, in the ES module test. With the messageId dropped or set
to a constant in the other two, the suite still passed 22/22, and no test read an ErrorResponse at all.
New: an ErrorResponse compared whole against the documented shape (header, endpoint, payload, no context), and one
test that sends two directives each to a light, an unreachable light and a scene and requires six different
version 4 UUIDs. The Response, StateReport, scene and change report tests check the messageId too; the pattern
lives in the harness.
Checked in a scratch copy: a missing or constant messageId at each of the three sites now fails the suite (the
missing one in AlexaStatusMessage does not compile). No change to src/ or dist/. npm test: 24 pass in 5.5 s.
