The channel manager's flat name/hash rows become fixed, column-aligned
lanes under one header line — name, openness, hash, unread badge, total
messages, last-message age, and a three-bar activity meter over the
trailing week — so a glance shows which channels are alive, not just
which exist. A new Repository.channel_stats() aggregates totals, the
week's slice, and the last timestamp per channel identity in one SQL
pass; rows read it through a small TTL cache with callable titles, so
a message arriving while the list sits open updates its row in place
(the conversation picker's trick, unread badge styling included).
Both menus adopt the config editor's persistent-backdrop pattern: the
list stays pushed while every sub-prompt floats over it as a modal
popup instead of replacing the screen. The detail screen leads with a
vital-signs line (slot, totals, unread, last activity) and lays its
actions out in the Device-actions two-lane style, with the live unread
badge on Open in chat and the destructive Clear row tinted err.
