fix(ci): run integration tests with Firebase Extensions emulator

Auth tests were starting only the functions emulator, so extension env
vars never reached Cloud Functions and Stream sync timed out. Start the
extensions emulator, drop duplicate functions deploy config, and call
ext-auth-chat-getStreamUserToken in the correct LOCATION region.

 Use Node.js 20 when running the test suite locally. The repo includes a top-level `.nvmrc` to keep the extension packages, CI, and emulator runs aligned on the same runtime.
 
+Auth integration tests start the **Extensions** emulator (`--only auth,functions,extensions`) so Stream API credentials from `extensions/*.env.local` are passed into extension functions. Callable tests must target `ext-auth-chat-getStreamUserToken` (region = `LOCATION` in env files).

 ## Locally
 
 You'll need the following files to set the right environment variables.
