- RingBuffer: Circular buffer for streaming data
- ScopedArena: RAII pattern for temporary allocations
Dirty Rectangle System:
- Context now tracks dirty regions for partial redraws
- Automatic rect merging to reduce overdraw
- invalidateRect(), needsRedraw(), getDirtyRects() API
- Falls back to full redraw when > 32 dirty rects
Benchmark Suite:
- Timer: High-resolution timing
- Benchmark: Stats collection (avg, min, max, stddev, median)
- FrameTimer: FPS and frame time tracking
- AllocationTracker: Memory usage monitoring
- Pre-built benchmarks for arena, pool, and commands
Context Improvements:
- Integrated FrameArena for zero-allocation hot paths
- frameAllocator() for per-frame widget allocations
- FrameStats for performance monitoring
- Context.init() now returns error union (breaking change)
