Liminal Suite v1.15.15

• Replaces Gaze's fail-open terminal recovery with a fail-secure safety curtain. If Android cannot relaunch the protected app, Gaze remains active and its existing touch-lock overlay turns solid black, blocking both interaction and view without locking the device.
• Keeps the ordinary Gaze dismissal routes available beneath the safety curtain: bottom-hold authentication, the configured volume-key shortcut, and the authenticated upward dismissal gesture continue to work, avoiding both an exposed phone and an unlock/relock loop.
• Aligns Dusk's Quick Settings click path with Ember: the live tile renders the accepted state before persistence, service, notification, or history work; preference persistence no longer performs a blocking disk commit; and a tile click never requests a redundant SystemUI rebind.
• Coalesces external Dusk tile refreshes to one 40 ms listening request and publishes actual compositor attachment directly to a currently open tile, reducing the first-click delay observed after rapid Ember use without adding polling or background work.
