Subject: [PATCH] fix(launch): use native window drag for HUD grip on Linux

BrowserWindow.setPosition(), which the grip's pointer-capture drag
relies on, is a no-op on Wayland compositors -- clients can't
reposition their own top-level window outside an OS-initiated
interactive move. Fall back to -webkit-app-region: drag there, same
mechanism the HUD bar's border already uses successfully.

Fixes #140
