Add real-time performance profiling infrastructure to monitor frame times, render performance, and identify bottlenecks. Features: - Profiler.h: ScopedTimer RAII helper for automatic timing measurements - ProfilerOverlay: F3-togglable overlay displaying real-time metrics - Detailed timing breakdowns: grid rendering, entity rendering, FOV, Python callbacks, and animation updates - Per-frame counters: cells rendered, entities rendered, draw calls - Performance color coding: green (<16ms), yellow (<33ms), red (>33ms) - Benchmark suite: static grid and moving entities performance tests Integration: - GameEngine: Integrated profiler overlay with F3 toggle - UIGrid: Added timing instrumentation for grid and entity rendering - Metrics tracked in ProfilingMetrics struct with 60-frame averaging Usage: - Press F3 in-game to toggle profiler overlay - Run benchmarks with tests/benchmark_*.py scripts - ScopedTimer automatically measures code block execution time This addresses issue #104 (Basic profiling/metrics). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
