Nuvio Linux v0.1.17-alpha (release 4)

Targeted fix for issue #12 (screen sleeps during playback on KDE/Flatpak).

The Flatpak previously held org.freedesktop.ScreenSaver (a compat no-op on Plasma 6) and org.freedesktop.PowerManagement (no longer implemented on Plasma 6.7), so PowerDevil ignored the inhibitor and the screen kept blanking. This build uses KDE's native org.kde.Solid.PowerManagement.PolicyAgent.AddInhibition — the exact call xdg-desktop-portal-kde makes internally for the Inhibit portal — which powerdevil bridges to logind on the host, so it works from the sandbox.

This release ships only the Flatpak (the affected format). Other formats will be rebuilt in the next full release.
