- Add a one-shot `search` action (site=naver/google/daum/youtube/bing) that
navigates the on-screen browser straight to the results page, so a small
model can satisfy "search X on Naver" in a single tool call instead of a
fragile navigate->type->enter chain.
- Sharpen the tool description to steer the router to controlBrowser (not
webSearch) for anything that should happen IN the visible browser.
- System prompt: answer in one short sentence (voice assistant) — also cuts
TTS time.
