Senders missing from the member list (left/removed) fell back to msg.from verbatim, and nameless members arrive from the REST API with the uid itself as display_name. Resolve both through a shared groupSenderLabel helper that substitutes a fixed placeholder for uid-shaped names (message bubbles, quoted replies, history search).
Server friend.request.* signals ride {info} frames addressed to the
recipient's own user id, but the SDK dispatcher resolves that topic via
its topic cache, where the me topic lives under the literal me -- the
lookup missed and the frame was dropped before any listener could see
it, so the 新朋友 badge and NewFriendsView list only updated after a
manual refresh or relogin. topics.ts now forwards frames whose topic is
not in the SDK cache (isTopicCached) through the connection-level
onInfoMessage hook to the same infoListeners used by topic-level
routing (no duplicate delivery), and AppShell invalidates the shared
['friend-requests'] query namespace on friend.request.* events, keeping
the pending badge live on any page. Zentao #3.
