Strut windows committed zero height to layer-shell during
early init, causing a protocol error and session exit. Wrap
height and exclusionZone in Math.max(1, ...) for top bar
and dock.
Persisted gamingModeEnabled=true with hardcoded
gameCenterOpen=false hid panels with no overlay visible.
Initialize gameCenterOpen from the stored setting.
Fix HUD visibility regression from an emergency visible:true
override. Various null-guard and positioning fixes from
static analysis across the gaming shell QML.
Add a gamingModeEnabled bool and a gamingDismissHintEnabled bool to
the shell settings plugin, persisted in plasmamobilerc [General],
following the same pattern as convergenceModeEnabled.
Two new quick settings tiles:
- org.kde.plasma.quicksetting.gaming: toggles gaming mode on/off,
shows explicit on/off label matching the convergence tile style.
- org.kde.plasma.quicksetting.gaminghint: shown while gaming mode
is active; dismisses the Game Center hint.
Both tiles are added to the default group in quicksettings config.
