Alessandro baac20f7a4 Fix Office artifact creation and canvas closing ... Add an explicit close button to the right canvas toolbar, next to the undock control, and cover its label, handler, and ordering in the canvas regression test. Treat document_artifact tool_args.method as an action alias so calls like method=create with format=xlsx create workbooks instead of falling back to LibreOffice status. Add regression coverage for the exact XLSX creation shape.		2026-05-02 14:08:35 +02:00
