Typed wrappers for /api/v1/social/* on arcadia-app. Built over the
generic client.GET/POST surface rather than openapi-fetch — the spec
hasn't been regenerated to cover these endpoints, but the shapes
mirror the Phoenix JSON modules exactly and can migrate to the typed
surface later without caller changes.
Factory `createSocialBindings(client)` returns a SocialBindings
object with one method per operation:
Profiles: getMyProfile, updateMyProfile, getProfile, listProfiles
Articles: listArticles, getArticle, createArticle, updateArticle,
deleteArticle
Board: listFeed, getThread, createPost, reply, updatePost,
deletePost
Favourites: listFavourites, addFavourite, removeFavourite
Subs: listSubscriptions, addSubscription, removeSubscription
Notifs: listNotifications, markNotificationRead,
markAllNotificationsRead
addSubscription takes an optional `lastSeenDnaHash` so callers can
record "the version I just vetted" — the platform's
on_dna_change fanout only pings users whose stored hash differs
from the new value, so passing it on subscribe means the user only
hears about *real* changes, not a notification at the value they
were already looking at.
Wire types mirror the Phoenix JSON modules; SocialNotificationKind
is `"mention" | "post_reply" | "dna_change" | (string & ...)` so
the union stays open to future kinds added platform-side.
