fyi.opensocial.watchConversation

Ask to be told, on the live stream (/space-events), whenever something is written in a conversation: a space one of its people owns, which the host has been registered to hear (com.atproto.space.registerNotify). Each ping is `event: conversation` with `{ space, repo }` and nothing of what was said. Lasts a day; ask again to keep it.
