A client that updates a notification through replaces_id does not produce a
second onNotification: Quickshell writes the new content onto the Notification
object the shell is already holding. The card draws a snapshot copied out of
that object — deliberately, since a live QObject in a ListModel role becomes a
dangling pointer the moment the server destroys it — so the toast kept showing
the superseded text, and archived it to history when it left the screen. A
Slack thread that updates in place read as stuck.
Every property the card draws is now watched on the notification we hold, and
a change rewrites both the model row and the file the popup was persisted
under. The file name is that popup's identity, so the rewrite lands in place:
a shell restart restores the version last shown, and so does the copy that
reaches history.
The countdown starts over when the content changes. New text arriving a second
before the toast was due to expire deserves a full look, not the remainder of
the clock the text it replaced had nearly run through.
