* Add session.redirect affordance (issue #710) Route send through session.redirect while a turn is streaming and the prompt is plain text (no attachments, not a /command); otherwise prompt.submit. Adds WsMethods.SESSION_REDIRECT + HermesWsClient.sendRedirect. No separate button — the composer already sends mid-turn, so send just does the redirect. * fix(chat): capture typing state before sendMessage for redirect Capture wasStreaming state before updating uiState.isAgentTyping so normal sends call prompt.submit. --------- Co-authored-by: M57 <hy4ri@users.noreply.github.com>
