Subject: [PATCH] ac-electron: experimental 'Launch Native Notepat' tray item
 (macOS)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wires a tray hook that spawns a macOS ac-native binary with notepat.mjs.
ac-native is currently Linux-only bare metal — when a mac target is built
and dropped at one of these paths it just starts working:

  1. $AC_NATIVE_BIN
  2. <repo>/fedac/native/build/ac-native-macos
  3. <repo>/fedac/native/build/ac-native
  4. /usr/local/bin/ac-native

Until then, the menu item shows a dialog explaining how to install.

Appears under Experimental in the AC tray, and directly under 'Open
Notepat Overlay' in the Notepat tray. Disabled on non-macOS.
