Notifications could only be tried through an active quiet window with quiet_mode = toast and a daemon restart. `talk test --toast` sends a test notification directly through the same notify path, reports the tool (notify-send / Notification Center / Windows toast) and the result, and exits 1 with a hint when no tool exists or the call fails.
