site: 2026-10-30 wiki refresh - new Project Goals, Performance and Interfaces and Stability pages; GSP explainer expanded (bare-metal behaviour + the two emulation modes); graphics pages (Graphics Execution, OpenGL, Vulkan, DirectX) with two new diagrams; status refresh across 15 pages; canonical docs updated (README status table, purpose-and-scope, performance contract); published to open-iov.org (67 pages, 0 problems)
