Electron 进程缺少 com.apple.security.cs.debugger entitlement， 导致 ScanMemoryForImageKey 中的 task_for_pid 调用失败（kr=5）。 新增 image_scan_helper 子进程包装程序（与 xkey_helper 方案一致）： - 新建 resources/image_scan_helper.c：dlopen libwx_key.dylib 并调用 ScanMemoryForImageKey，通过 JSON stdout 返回结果 - 新建 resources/image_scan_entitlements.plist：包含 debugger 和 allow-unsigned-executable-memory entitlements - 编译为 universal binary（x86_64 + arm64）并 ad-hoc 签名 - 修改 keyServiceMac.ts _scanMemoryForAesKey()：优先 spawn image_scan_helper 子进程，失败时 fallback 到直接调 dylib Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
