Add Brave CDP automation, replace Oracle browser mode
Connects to user's running Brave via Chrome DevTools Protocol to automate ChatGPT interaction. Uses puppeteer-core to open a tab, send the prompt, wait for response, and extract the result. No cookies, no separate profiles, no copy/paste. Just connects to the browser where the user is already logged in. One-time setup: relaunch Brave with --remote-debugging-port=9222 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
