Reverts the temporary cap from PR #1 so the daemon advertises the real panel mode again.
Depends on a gamescope payload built with GameNative/gamescope A37 (flat textures cleared instead of staged through the fixed upload buffer); without it, outputs wider than 1080p abort in uploadBufferData. Keep as draft until that payload ships.
