John McCardle 7d57ce2608 feat: Implement SpatialHash for O(1) entity spatial queries (closes #115) ... Add SpatialHash class for efficient spatial queries on entities: - New SpatialHash.h/cpp with bucket-based spatial hashing - Grid.entities_in_radius(x, y, radius) method for O(k) queries - Automatic spatial hash updates on entity add/remove/move Benchmark results at 2,000 entities: - Single query: 16.2× faster (0.044ms → 0.003ms) - N×N visibility: 104.8× faster (74ms → 1ms) This enables efficient range queries for AI, visibility, and collision detection without scanning all entities. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>		2025-12-28 00:44:07 -05:00
