Plugins

Vision-first Mac computer use, for when the accessibility tree is unavailable. Ships 11 desktop_* tools - window list, screenshots, OCR text targeting, numbered elements, coordinate clicks, typing, scrolling, drag - plus a Codex-style cursor overlay with spring animation. Clicks are delivered to the target process, so the real pointer never moves and nothing steals focus. In DSH it shows up as Mac Desktop Control with a settings page that checks the engine and the Screen Recording / Accessibility permissions, with a button that opens the matching System Settings pane. One-time prerequisite: no binary is bundled; clone the repo and run ./install.sh once to compile the dsh-cu engine and the overlay with swiftc (Xcode Command Line Tools - the script stops with a clear message when swiftc is missing or the system is not macOS). Until that is done the desktop_* tools fail with exactly these steps.
