Implements GL timer queries end to end: a frontend query registry (modeled on the sync module - mutex-guarded objects wrapping opaque backend handles behind optional function pointers) serving glGenQueries/glBeginQuery/glEndQuery(GL_TIME_ELAPSED)/glQueryCounter (GL_TIMESTAMP)/glGetQueryObject*/glGetQueryiv with GL 3.3 error semantics and a graceful zero-result fallback when a backend cannot time. DirectGLES backs spans with GL_EXT_disjoint_timer_query (context- generation-stamped handles, bounded result waits). DirectVulkan gets a VkTimerQueryManager: per-frame-in-flight timestamp query pools reset at command-buffer begin (outside render passes), records harvested by frame serial before their pool recycles, elapsed = masked tick delta x timestampPeriod; handles are stamped with a renderer generation that also now guards fence syncs across renderer recreation. GL_QUERY_ COUNTER_BITS reports 0 unless the live backend can actually time (dynamic IsTimerQuerySupported hook), and a failed blocking read keeps the handle alive so the real value stays reachable once the frame submits. GL_ARB_timer_query is advertised only when the device supports timing and MOBILEGL_DISABLE_TIMERQUERY is unset - LWJGL keys Minecraft's F3 'GPU: x%' line off exactly that extension string; verified on device (Adreno 830) on both backends.
