Renders broker traffic as a chat timeline and makes the user a first-class
participant. The broker grows a Stream<TeamMessage> and a recipient field,
auto-registers a virtual `user` member, and gains sendAsUser. A Flutter-free
TeamChatModel (owned by the orchestrator) accumulates the feed and exposes
postAsUser with @-routing (a new at_commands helper mirroring slash) and an
optional interrupt that cancels the target's turn before delivery. One model
backs two surfaces: a compact cockpit widget that pops out into a full
workspace chat pane. CLI parity via clide.team-chat.open / .post.

Session lifecycle now runs entirely on the stream-json model: argv
selection picks --resume <id> for an existing transcript and
--session-id <uuid> for a fresh one, and the managed-session orchestrator
owns spawn/close. With the transport off tmux, remove the tmux session
lifecycle (reaping, kill-all-for-repo) and the tmux-polling team observer;
kill-all-sessions now closes sessions through the orchestrator. Team
membership is orchestrator-driven since the coordination broker landed.
Amends D-41 (tmux persistence -> --resume). T-167.
