HotReloadStatusMsg class

Message sent when the hot reload system changes state.

Models can pattern-match on this in Model.update to display reload status in the TUI view. The message is dispatched through the normal message queue and is never dropped by input coalescing.

Example

@override
(Model, Cmd?) update(Msg msg) {
  return switch (msg) {
    HotReloadStatusMsg(status: HotReloadStatus.succeeded) => (
      this,
      null,
    ),
    _ => (this, null),
  };
}
