mali-v6 fixes the one open item from mali-v5: the in-game Copy-logs button.

What changed

• The in-game Debug Logs dialog action row (Copy / Clear / Pause / Close) is now pinned to the bottom of the panel and always visible. Previously, in landscape, the log list filled the whole height and pushed the Copy button off the bottom edge. The log list now scrolls within the space above the buttons.
• Everything else is identical to mali-v5 (shader-v3 bcn_layer, ETC2-Milestone-2 wrapper, selectable log location, co-located DXVK/DXGI/VKD3D logs).

Install

• versionCode 39 (same as 2.4) and same signature, so it installs over 2.4 or mali-v5 with no uninstall and your containers are preserved.
• This is a pre-release: it is not offered to stable users and does not touch the 2.4 in-app updater.
• If you are on the earlier mali-v4 CI artifact (vc41), uninstall that first (vc41 to vc39 is a downgrade and Android will block it).
