steering demoable: the Enter branch keys on BUSY (own-stream clears turnInFlight — Enter was swallowed during our own turn), and the button follows the text (owner live report 2026-10-03)

Browse Source 
Root cause: doSteerOrSend branched on turnInFlight, but the local dedup
(chat.tsx ~370) clears that flag the moment the own stream takes over —
during our own turn busy was true and turnInFlight false, so Enter fell to
the plain-send path whose busy guard returned silently. Branch on busy:
own stream AND foreign/wake turns both have a live agent registered by the
time the send's POST resolved, so the steer lands (a raced settle 409s and
falls back to the plain send).

The button now follows the text: busy + typed text = Send (click steers —
steering must be clickable, not Enter-only); busy + empty = Stop. ESC keeps
its confirm-popup abort in every state, so stop is never unreachable.
