Windows toast notifications silently no-op unless the app sets an
AppUserModelID — new Notification().show() returns without error and
nothing appears. The desktop's native-notification system (approval,
turn-done, input, etc.) was therefore dead on Windows while working on
macOS/Linux.
Set the AUMID to the build appId (com.nousresearch.hermes) on Windows
right after app.setName, so toasts route to the installed Start Menu
shortcut. No-op on macOS/Linux, which don't require it.
