The unconditional startup scan introduced duplicate tray icons on normal boot because apps were still registering their own SNI items when the scan ran.
Use CLOCK_BOOTTIME − CLOCK_MONOTONIC to detect whether the system has ever been suspended. The startup scan now only runs when the difference exceeds 5 s, meaning at least one suspend/resume cycle has occurred.
On a fresh boot the difference is ≈ 0 and the scan is skipped entirely.
