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

+# webdriver-bidi-protocol
+
+This repository contains TypeScript types conforming to the [WebDriver
+BiDi](https://w3c.github.io/webdriver-bidi/) specification. It also
+supports WebDriver BiDi extension modules defined in other
+specifications:
+
+- [Permissions](https://w3c.github.io/permissions/#automation-webdriver-bidi)
+- [Web Bluetooth](https://webbluetoothcg.github.io/web-bluetooth/#automated-testing)
+
+## Installation
+
+```
+npm install webdriver-bidi-protocol
+```
+
+## Usage
+
+In your TypeScript client implementation, you can now import WebDriver
+BiDi types:
+
+```ts
+import {Commands} from 'webdriver-bidi-protocol';
+
+async function sendCommand<T extends keyof Commands>(
+  method: T,
+  params: Commands[T]['params']
+): {result: Commands[T]['returnType']} {
+  // Implementation for sending the data using WebSockets.
+}
+
+// Now TypeScript validates that the params match the spec for 'browsingContext.print'.
+await sendCommand('browsingContext.print', {context: 'xxx'});
+```
+
+## Versioning
+
+This package patch version will be incremented whenever there are
+specification updates.
