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

+socks-proxy-agent
+================
+### A SOCKS proxy `http.Agent` implementation for HTTP and HTTPS
+
+This module provides an `http.Agent` implementation that connects to a
+specified SOCKS proxy server, and can be used with the built-in `http`
+and `https` modules.
+
+It can also be used in conjunction with the `ws` module to establish a WebSocket
+connection over a SOCKS proxy. See the "Examples" section below.
+
+Examples
+--------
+
+```ts
+import https from 'https';
+import { SocksProxyAgent } from 'socks-proxy-agent';
+
+const agent = new SocksProxyAgent(
+	'socks://your-name%40gmail.com:abcdef12345124@br41.nordvpn.com'
+);
+
+https.get('https://ipinfo.io', { agent }, (res) => {
+	console.log(res.headers);
+	res.pipe(process.stdout);
+});
+```
+
+#### `ws` WebSocket connection example
+
+```ts
+import WebSocket from 'ws';
+import { SocksProxyAgent } from 'socks-proxy-agent';
+
+const agent = new SocksProxyAgent(
+	'socks://your-name%40gmail.com:abcdef12345124@br41.nordvpn.com'
+);
+
+var socket = new WebSocket('ws://echo.websocket.events', { agent });
+
+socket.on('open', function () {
+	console.log('"open" event!');
+	socket.send('hello world');
+});
+
+socket.on('message', function (data, flags) {
+	console.log('"message" event! %j %j', data, flags);
+	socket.close();
+});
+```
