Overview

updates.ChannelDifference — the reply to updates.getChannelDifference: a channel/supergroup's backlog since a given pts. Channels aren't pushed to a fresh session, so the client pulls this. Three variants:

channelDifference        — new_messages + other_updates + chats + users, with the new pts
channelDifferenceEmpty   — nothing new since pts (just pts/final/timeout)
channelDifferenceTooLong — gap too large: a Dialog snapshot + a messages slice
                         + chats + users; the caller resyncs pts from the dialog

Mirrors UpdatesDifference: reads only the surfaced fields and advances the rest via Schema#skip (zero-drop, robust to an unmodelled tail).

Channel messages ride in new_messages, but message-bearing updates can also appear in other_updates — mine those too, like UpdatesDifference.
