refactor(desktop): replace get-windows and uiohook-napi, isolate xa11y

get-windows brought node-pre-gyp, a GitHub-downloaded Windows addon, and
an ad-hoc-signed Mach-O spawned per capture, for one function. The
snapshot service now resolves the foreground window itself: a short
osascript JXA lookup on macOS and seven Win32 calls through the ffi-rs
loader we already ship on Windows.

uiohook-napi installed a system-wide keyboard hook from a single-maintainer
package for the Windows modifier-pair shortcut. The forked listener now
polls GetAsyncKeyState at 20 Hz, mirroring the macOS design.

xa11y no longer loads in the main process. Windows region capture runs in
a forked RegionSnapShotWorker with a warm standby and a deadline, and the
in-process UIA focus fallback is gone; the worker thread covers that path.
WindowsWindowIcon.ts is dropped in favour of app.getFileIcon, which was
already the fallback.
