- Initial build

Would fail if clearing all notifications with `C` which would hide the
window. When later opening the Control Center, shortcuts wouldn't work
until manually focused. Might be a Sway bug, but this fixes it on my
end.

Instead of getting the first/last notification in the AnimatedList, we
get the first/last non-destroyed item

* Remove unneeded code + DBus methods that should be internal

* Moved CC and NotiDaemon out of SwayncDaemon

* Moved NotificationCloseButton into its own file

* De-singletonified the NotificationWindow Widget

* Fixed formatting

* Hide the C compilers warnings when compiling

* Revamped and vastly simplified notification removal logic

* Redirect stdout to /dev/null in uncrustify GitHub Action

Makes it easier to know what files fail without needing to search the
output logs

* Changed enum NotificationType POPUP -> FLOATING
