Core optimization: - Use CGDisplayStream instead of per-frame CGDisplayCreateImage - Push model: CPU sleeps when screen is static (condition_variable wait) - IOSurface capture avoids expensive image creation per frame - ~47% CPU reduction during active remote desktop (45% → 24%) Additional optimizations: - vImageVerticalReflect (SIMD) replaces manual row-by-row flip - Cache CGColorSpaceRef to avoid per-frame creation/release - Cache tempBuffer to avoid per-frame memory allocation - Throttle getCursorTypeIndex to 250ms (Accessibility API is expensive) Bug fixes: - Fix unreliable screen capture permission check (use actual capture test) - Improve permission logging Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
