Zombie Panic 10210 calls native IBorder slot 6 as GetName(), but the SDK inserted ParseSideSettings(int, KeyValues*, IScheme*) there. This dispatched a no-argument call to a three-argument implementation and crashed during client UI initialization. Remove the helper from the public interface; Border keeps its private nonvirtual parser and native slots 0–7 retain their original order.

Rebuild SDK consumers with this header. MetaHookSv/VGUI2Extension#34 restores native missing-image behavior and adds a regression that calls border slots 6/7 using the native ABI. MetaHookSv/MetaHookSv#968 pins both component fixes. Merge this SDK fix before the dependent plugin PR.

Validation with both component changes:

• Aggregate Debug/Win32 build with MSVC v143 and Windows SDK 10.0.26100.0 passed.
• All 11 VGUI2Extension CTests passed; the new native-slot regression failed against the old header and passed with this fix.
• Pinned clang-format checks passed for MetaHook and VGUI2Extension.
• Deployed DLLs let the original zp client Start() return under CDB without runtime patches, traversing both previously failing paths.

Full game startup remains blocked later by a separate Renderer error: missing client gamedata symbol GameStudioRenderer_StudioDrawModel. Main-menu/map/visual regression is not claimed.
