The activity panel, and continuing an agent chat in a terminal

The activity panel beside a chat, from /api/v2's activity routes: Context
(used share, tokens against the window, a segmented bar and a row per
category), Outputs (the files written, lines added and removed, each opening
in the viewer), Background tasks (a team's members as a tree, helpers and
commands: state, elapsed time counting on between reads, model, latest step,
what it is writing, its whole conversation read-only, Stop -- a member after
a confirmation, as it takes those under it), the team's room (who to whom,
reports marked, the words through the page's own markdown) and the plan.

The chat follows GET /chats/{chat}/activity/events while it is open: the strip
above the message box sums the agents up and opens the panel; a new version
reads the panel again while it is open, the costly context part on opening,
after a reply and at most every 15 s. The stream is reopened when the server
closes it, and more slowly while it fails. Beside the chat on a wide window
(the viewer then goes over the chat), over it below --bp-wide, a full-height
sheet at --bp-narrow. The header's Activity button, the palette and Escape
open and close it.

An agent chat with a device session (device_session_id) can be continued in a
terminal: the chat's menu and a header button show 'cd <folder> && lembas -s
<id>' to copy, with lembas the CLI as it starts here (on PATH, else the app's
own copy by its path). Shown rather than run: no terminal opens the same way
on every desktop.
