Launching PassKey when it is already running in the system tray now brings the existing window to the foreground (via a named EventWaitHandle) instead of silently spawning a second invisible process. This was the root cause of the "app installs but doesn't start" symptom reported on v1.0.7. A startup crash log is also written to %LOCALAPPDATA%\PassKey\startup-crash.log when Application.Start() throws before the main window is created, making silent startup failures diagnosable without a debugger.
