Overlay Messaging: custom action handler for deep linking

The Overlay Messaging Web SDK now supports a custom action handler. Register setActionHandler to override the default link behavior on a call-to-action tap — for example, to deep-link into your app with your own router or open the URL in an in-app browser. You override only the actions you want; anything you don't override keeps the SDK default.

Impact: Optional. Existing integrations are unchanged — links continue to open as before unless you register a handler.

For the API and recipes, see the Getting Started with Overlay Messaging guide.
