/** * Global Escape → abort. Mirrors Cowork's `escAbort.ts` but without Electron: * CGEventTap via `@ant/computer-use-swift`. While registered, Escape is * consumed system-wide (PI defense — a prompt-injected action can't dismiss * a dialog with Escape). * * Lifecycle: register on fresh lock acquire (`wrapper.tsx` `acquireCuLock`), * unregister on lock release (`cleanup.ts`). The tap's CFRunLoopSource sits * in .defaultMode on CFRunLoopGetMain(), so we hold a drainRunLoop pump * retain for the registration's lifetime — same refcounted setInterval as * the `@MainActor` methods. * * `notifyExpectedEscape()` punches a hole for model-synthesized Escapes: the * executor's `key("escape")` calls it before posting the CGEvent. Swift * schedules a 100ms decay so a CGEvent that never reaches the tap callback * doesn't eat the next user ESC. */
