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.

Implements ADR-008. native/input-helper is a self-contained .NET 9 console exe
speaking the identical JSON-over-stdin/stdout protocol as the old PowerShell
helper (ping/cursor/runtime/focus/click/scroll/bounds/capture), so the
InputHelperService interface is unchanged.
- Win32 interop compiled once (native exe), not per call.
- PerMonitorV2 DPI via manifest so click/capture coordinates stay correct on
mixed-DPI multi-monitor setups.
- capture returns base64 PNG bytes inline (imageBase64) instead of writing a
temp file per frame; the client handles both base64 and the PowerShell path.
- InputHelperClient prefers the exe and falls back to the embedded PowerShell
helper when the exe is absent, so the app still runs without the .NET build.
- main.ts resolves the exe (INPUT_HELPER_EXE env -> packaged resources/input-helper
-> native/input-helper/bin/publish). electron-builder ships it via extraResources.
- npm run helper:build; README documents the build + fallback.
Verified end-to-end through the compiled client: sidecar spawns, runtime info
and a base64 primary-screen capture return correctly. Build stays green.

Import the existing Electron + React + TypeScript app as the version-control
baseline before the scanner rework (C# input/capture sidecar, resolution-anchored
layout profiles, OCR preprocessing, eval harness, rescan-merge, GOOD interop).
Housekeeping in this commit:
- Remove orphaned temp_inputhelper_block.ts (duplicate of the input-helper script).
- Ignore .claude/scheduled_tasks.lock local session state.
- Add .gitattributes to normalize line endings (LF in repo).
