Focus the emitting tab when a notification is clicked

Resolve the OSC 9 onclick TODO: clicking a notification now brings the window to the front and selects the exact tab/pane that emitted the sequence. The title is read live from the tab each time instead of being captured once when the session is attached. Adds tabby-core as a dependency for AppService/HostWindowService.
