chat-client-noop-devtools.test.ts

// Regression coverage for the shipping default. The suite-wide setup file
// (`use-real-devtools-bridges.ts`) re-routes the no-op devtools factories to
// the real bridges, so no other test exercises the bridge production
// consumers actually get when they don't opt into devtools. Unmock here so
// `ChatClient` runs against the actual no-op bridge that ships as the
// default, instead of the real-bridge substitute the setup file installs.
