debugEncode static method

@visibleForTesting String debugEncode(GlassAdaptiveDiagnostic? diagnostic)

JSON-encodes diagnostic the way the registered extension responds.

Exposed for tests and for anyone building a DevTools panel against this bridge — a plain function, independent of VM service registration.

Implementation
