The Phoenix auth/identity/tenancy backend repo is being renamed
arcadia-app → arcadia-core (its primary OTP app is already arcadia_core).
Updates prose, doc paths, and git.sky-ai.com repo URLs. Deliberately
leaves the Rust crate arcadia-app-client and host arcadia-app.internal
(handled separately), and the kept namespace (issuer/release "arcadia").

Disambiguates the Phoenix/auth client lib from lib-arcadia-agents-client.
Dir lib-arcadia-client → lib-arcadia-core-client; alias updated in
tsconfig paths, vite config, app.css @source, imports, CI and docs.

Document createSocialBindings + useSocial pattern + the three new
TenantEventMap entries (social:notification, social:post,
social:article) so consumers know the channel events exist.
