fix: patch uiohook-napi to use listen-only CGEventTap on macOS

Fixes system-wide freeze when Accessibility permissions are enabled. Two changes to libuiohook/src/darwin/input_hook.c via pnpm patch: - Switch kCGEventTapOptionDefault to kCGEventTapOptionListenOnly - Strip mouse move/drag/scroll/left/right-click events from mask Listen-only taps are passive observers that cannot freeze the system. Keeps keyboard events and mouse buttons 3+ for PTT side buttons. Windows and Linux native paths are completely untouched.
