e5e796bad9 refactor: comprehensive test suite overhaul and demo system
Major changes:
- Reorganized tests/ into unit/, integration/, regression/, benchmarks/, demo/
- Deleted 73 failing/outdated tests, kept 126 passing tests (100% pass rate)
- Created demo system with 6 feature screens (Caption, Frame, Primitives, Grid, Animation, Color)
- Updated .gitignore to track tests/ directory
- Updated CLAUDE.md with comprehensive testing guidelines and API quick reference

Demo system features:
- Interactive menu navigation (press 1-6 for demos, ESC to return)
- Headless screenshot generation for CI
- Per-feature demonstration screens with code examples

Testing infrastructure:
- tests/run_tests.py - unified test runner with timeout support
- tests/demo/demo_main.py - interactive/headless demo runner
- All tests are headless-compliant

e9e9cd2f81 feat: Add comprehensive profiling system with F3 overlay
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).
