The following command fetches the Docker image and starts a new container exposing Lightpanda's CDP server on port `9222`.
The `--privileged` option is required because the browser requires `io_uring` syscalls which are blocked by default by Docker.

// For JS imports (both static and dynamic), we currently block to get the
// result (the content of the file).
//
// For static imports, this is necessary, since v8 is expecting the compiled module
// as part of the function return. (we should try to pre-load the JavaScript
// source via module.GetModuleRequests(), but that's for a later time).
//
// For dynamic dynamic imports, this is not strictly necessary since the v8
// call returns a Promise; we could make this a normal get call, associated with
// the promise, and when done, resolve the promise.
//
// In both cases, for now at least, we just issue a "blocking" request. We block
// by ticking the http client until the script is complete.
//
// This uses the client.blockingRequest call which has a dedicated handle for
// these blocking requests. Because they are blocking, we're guaranteed to have
// only 1 at a time, thus the 1 reserved handle.
//
// You almost don't need the http client's blocking handle. In most cases, you
// should always have 1 free handle whenever you get here, because we always
// release the handle before executing the doneCallback. So, if a module does:
// import * as x from 'blah'
// And we need to load 'blah', there should always be 1 free handle - the handle
// of the http GET we just completed before executing the module.
// The exception to this, and the reason we need a special blocking handle, is
// for inline modules within the HTML page itself:
// <script type=module>import ....</script>
// Unlike external modules which can only ever be executed after releasing an
// http handle, these are executed without there necessarily being a free handle.
// Thus, Http/Client.zig maintains a dedicated handle for these calls.
