feat(notifications): notify when focused on a different task

Previously, permission requests and prompt completions only fired a sound,
desktop notification, and dock badge if the window was unfocused. If the
user was viewing task A in PostHog Code while task B asked for input,
nothing surfaced — they had to manually check the other task.

Now also notify when the window is focused but the user is viewing a
different task (or no task at all). The window-focus path is unchanged.
