- Wire ChatMessageRemoteMediator into Pager for backward pagination (older messages on scroll up) with cursor-based paging tokens
- Fix mediator APPEND to pass messageId cursor via ByteBuffer encoding
- Eagerly load messages in OnChatOpened handler instead of waiting for state roundtrip, so fetch starts during navigation transition
- Prefetch first page of messages during feed sync for chats with no cached messages
- Hide ContactInfoContainer until messages have loaded to prevent flash
- Add hasMessages/getLatestMessageId helpers to ChatMessageDataSource
