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

+/**
+ * QuickJSDeferredPromise wraps a QuickJS promise [[handle]] and allows
+ * [[resolve]]ing or [[reject]]ing that promise. Use it to bridge asynchronous
+ * code on the host to APIs inside a QuickJSContext.
+ *
+ * Managing the lifetime of promises is tricky. There are three
+ * [[QuickJSHandle]]s inside of each deferred promise object: (1) the promise
+ * itself, (2) the `resolve` callback, and (3) the `reject` callback.
+ *
+ * - If the promise will be fulfilled before the end of it's [[owner]]'s lifetime,
+ *   the only cleanup necessary is `deferred.handle.dispose()`, because
+ *   calling [[resolve]] or [[reject]] will dispose of both callbacks automatically.
+ *
+ * - As the return value of a [[VmFunctionImplementation]], return [[handle]],
+ *   and ensure that either [[resolve]] or [[reject]] will be called. No other
+ *   clean-up is necessary.
+ *
+ * - In other cases, call [[dispose]], which will dispose [[handle]] as well as the
+ *   QuickJS handles that back [[resolve]] and [[reject]]. For this object,
+ *   [[dispose]] is idempotent.
