R8 the Mastodon API made real: featured tags, endorsements, notes, notify and languages, suggestions, the direct stream

Featured tags per persona (/api/v1/featured_tags, suggestions, tags/:name/feature, accounts' featured tags, max 10),
listed at /tattoos as Hashtags and sent as Add/Remove{Hashtag} to followers on the featured collection, as Mastodon
sends them; remote accounts' tags received and read from featuredTags. Endorsements (pin/endorse) and private notes
(PersonaNote) kept per persona and never federated; the relationship's notifying, languages, endorsed and note, with
follow's notify (status notifications) and languages (home filter). Reading preferences set on /clientapi. Suggestions
v1/v2 with dismissals and staff picks, never the persona or a sibling. conversation events on the direct stream.
translate, annual reports and the admin API answer. New collections backed up and removed with their persona.
