Previously, the browser waits for the server initialization to succeed before unlocking the loading process. When reloading the webview, since the server has already been initialized, it does not receive an initialization event and is stuck loading forever. Fix by moving to a hot flow that always returns the latest instance of AmazonQLanguageServer. While this could be any value, the idea is to bring us closer to the state where we can tie the lifetime of ChatCommunicationManager to the webview instance so that we can delete AsyncChatUiListener. Additionally this should also address the rare race condition where the server finishes startup before the webview finishes drawing.

So is this an await equivalent?

flows are like sequences, so this will wait until a value is available. this specific flow is set up to only ever have one value
