feat: controlBrowser tool — human-operable on-screen Chrome
Adds a general browser-control tool (navigate to any site, list/open/close/ switch tabs, close popups, click, type, scroll, screenshot) for the Go-Live Chrome, on top of the existing CDP + xdotool human-input layer (visible cursor, char-by-char typing). Closes the gap where "open Naver" had no tool and the model confabulated success. Also adds a system-prompt rule against claiming actions no tool actually performed.

"""Operate the on-screen (Go-Live) Chrome like a person would.
|
||||
|
||||
Only meaningful in screen-share mode (``STREAM_BROWSER`` true): it drives the
|
||||
on-screen Chrome via the Node CDP helper (``chrome-control.mjs``) so every
|
||||
action is visible on the broadcast. Pointer moves, clicks and typing are real
|
||||
xdotool input (visible cursor, char-by-char typing), never synthetic DOM
|
||||
events.
|
||||
|
||||
This is the general browser-control tool (navigate to any site, manage
|
||||
windows/tabs, click, type, scroll, screenshot). ``browseAndPlay`` remains the
|
||||
YouTube-playback shortcut.
