Reuse MediaSession/MediaObj to hold social posts & replies (post=MediaObj, comment=child MediaObj via MediaObjMsg.parent, provider linkage on MediaObjSocialRef). Adds SocialFeedAdapter sub-interface (feed ops kept off the DM SocialProviderAdapter path), MediaSessionSocialFeed (per-connection feed session), MediaObjSocialRef feed columns, SocialObjKind, and the expanded ProviderCapabilities matrix that drives per-provider UI feature-hiding.
