feat(RemoteActor): add bio, banner_url, followers_url, following_url, also_known_as fields

Bump to 0.3.1. These fields are available on DbActor at follow/ingest
time but were discarded when constructing RemoteActor. Now populated
in from_json and follow(), so consuming repos can store and return
rich actor profiles without extra queries.
