EmilyChatEnvironment 1.2.0 API

```
public class EmilyChatEnvironment

                    
```
The Emily widget bundle that the embedded android.webkit.WebView should load.
In practice the SDK loads a small HTML container (mobile-v<major>.html) that boots emily-v<major>.js and bridges native ↔ web. The container is versioned by the web SDK's MAJOR so a host app pinned to v1 keeps working across non-breaking widget releases.
Use Custom for staging branches, on-prem deployments, or pointing at a locally served vite preview build during development (note: cleartext http://10.0.2.2:5174/... requires a network-security-config opt-in in the host app, see the README).
Kept as a sealed class (rather than an enum) so Custom can carry a URL.
