A3S Office v0.54.1

Fixed\n\n- Stabilize the Windows A3S Test CDP adapter by invoking the pinned standalone browser directly and resolving on process exit, avoiding detached-session port polling and inherited stdio hangs.\n- Make the Writer text-box A3S Test contract discover responsive toolbar overflow and phone-surface scrolling before semantic actions.\n- Verify four desktop/phone scenarios with screenshots, accessibility, console, and page-error evidence.\n\nWindows CUA remains fail-closed as unsupported under the locked CUA Driver 0.10.0 matrix; browser-editor evidence is provided by A3S Test Web/CDP, with WPS COM kept as a separate reference workflow.
