Function parseHandlerPreferences

parseHandlerPreferences(event: NostrEvent): HandlerPreferences | undefined
Read the public entries of a handler-preferences event.

Unknown tags and malformed entries are ignored without discarding the event. An i entry counts only when its convention is queryless, fragment-free and names the event's archetype.
Parameters
- event: NostrEvent
  A kind-31129 event, already verified as the user's.
Returns HandlerPreferences | undefined
The preferences, or undefined when the event is not one.
Example
```
parseHandlerPreferences(event)?.handlers; // ['35129:…:notepad']
```
