Chord package for the macOS tray.
src/swift/tray/tray.swift scans menu-bar extras through the Accessibility API and activates them
with AXPress or a Core Graphics mouse event. NodeSwift exposes the operation as a Node-API function;
src/js/tray.ts loads the compiled tray.node add-on with process.dlopen, so tray actions run in
Chord's Bun process without an osascript hop.
