FakeJsEnvironment class

Web-only fake JS environment; on non-web platforms every method throws UnsupportedError with guidance.

On the web (under dart test -p chrome) this installs capability overrides plus a fake SharedArrayBuffer allocator so the real web code paths run without cross-origin isolation.
