This branch intentionally appends plugin-sourced context (plan-mode
notices, the skill catalog) after the prompt, so the request's last message
is no longer the user's text. The scripted adapter keyed every scenario off
messages.at(-1) only, missed its triggers, and fell through to the
ask_user_question default — the frozen 'Waiting for the first token' PTY
timeouts. It now scans all text since the last assistant message.
