- Introduces a SerializedEventData type that captures only serializable
properties from DOM/React events
- Updates `wrapEventHandler` in the host component registry to serialize
native events via serializeEvent() before passing them across the worker
boundary via postMessage, avoiding circular references and non-cloneable
DOM nodes
- Updates generated remote element event signatures to use
RemoteEvent<SerializedEventData> instead of bare RemoteEvent, giving
front-component authors typed access to event details
