AX-driven component tests for native macOS apps

Author and run reusable component UI tests for a NATIVE macOS app (Tauri, Electron, or any WKWebView/AppKit app) by driving the macOS accessibility (AX) tree — match elements by AXRole + name/label, act with AXPress, type with real key events. YOU (the agent) run everything; the user just converses. The harness is vendored into the app repo (default tests/native/) so the test library is versioned WITH the app and self-locating across sessions. USE THIS when asked to: "test the desktop/Tauri app", "write a UI test for the native app", "add an AX/accessibility test", "automate clicking through the app", "add this flow to the test library", "component test for the macOS app"…
