Subagents by name; the activity panel as the reference: header button, compact, tasks
- "Subagents" everywhere a person reads it (chip, popover with Fewest/Most, scheduled task,
  panel); offered per the server's `subagents` on a model or chat where it says it, else as
  before; the fields' most is the server's cap, else 32. No subagent-model setting.
- Panel: always reachable from the header's button; the line above the composer only while
  something runs; Environment for an agent chat; Context with "N until auto-compact" and a
  Compact button (POST /chats/{chat}/compact; a server without it is said so); Background
  tasks under Running with elapsed time and a stop square each, unfolding to kind, step,
  live text and conversation, nested tasks folded under their parent, Finished N folded;
  Room and Plan as sections.
- i18n: 24 new sentences x 8 languages, 9 retired; CHANGELOG [Unreleased].

// One chat: its transcript, the reply being written (followed as the server streams it), the
// cards that wait for an answer, and the composer with the chat's settings as chips under the
// text (folder, mode, model, effort, agents). And a new chat, which is the same page empty: a
// greeting, the choice of an agent chat on this computer or a chat on the server, and the composer.
//
// The transcript is the server's /api/v2 serialisation (tests/fixtures/api_v2 in the server's
// repository is the contract): a person's message is their text as typed; a reply is its steps --
// thinking, text (markdown, model output), tool calls, messages taken in while it ran.
