Three separate faults, all mine:
set_application was never called, so mac-notification-sys looked up an
app named "use_default", failed, and posted every notification as
com.apple.Finder - wearing Finder's alert style rather than this app's.
NSUserNotificationCenter suppresses the banner whenever the posting app
is frontmost unless the delegate implements shouldPresentNotification:.
The crate's delegate implements only delivery and activation, so the
method is added to its class at runtime. Without it, Gmail notifying
while you sit in Odoo - same window, still frontmost - is never seen,
which is the case the whole design exists for.
send_notification only waits for a response when the options ask it to.
Passing None returned instantly with NotificationResponse::None, so the
click branch was unreachable. Waiting parks a thread and a notification
left unread never resolves, so waiters are capped at 32.
The diagnostic now records the raise before blocking, since with
wait_for_click a notification sitting on screen otherwise read as
"none yet".
