Auto-scan aborted immediately with "Genshin konnte nicht in den Vordergrund
geholt werden". Root cause: the focus call runs in the background input/capture
helper process, and Windows' foreground lock silently refuses SetForegroundWindow
from a process that is neither foreground nor the last input source. When the user
clicks "Auto-Scan starten" the Electron window is foreground, so the helper's plain
SetForegroundWindow is dropped and focus stays false.
Fix (both the C# sidecar and the PowerShell fallback): before SetForegroundWindow,
attach our thread's input queue to the target (and current-foreground) window
thread with AttachThreadInput and clear SPI_..FOREGROUNDLOCKTIMEOUT, then restore.
This is the same technique Inventory Kamera and other reliable automators use; it
is what our helper was missing after the old ALT-tap workaround was removed on the
wrong assumption that equal integrity level is sufficient (that only covers UIPI
input injection, not foreground changes).
Sidecar recompiled + republished; electron build green.
