pi-ai 1.0.0 adds Sign in with ChatGPT to the `openai` provider, and that
login refuses to start unless the app supplies a stable installation UUID
through LoginOptions.getDeviceId. The harness keeps no installation ID
meant for a third-party account sign-in, so the route offers its API-key
login only; a Loader-composed test pins the offered methods.
catalogProvider(), catalogModels(), and catalogProviderIds() now read one
index that leaves out providers without a chat model, so a hand-declared
route under such a key inherits nothing from pi-ai. The browser-worker
stub gains the builtinModels refusal llm-pi-ai imports and drops the
getBuiltinProviders reader nothing imports. The tool-argument streaming
spec also covers the patched Anthropic Messages path.
