Elimina el kernel Metal O(N²) de boids en GPU que causava GPU timeout a macOS amb >50K boles, arrossegant WindowServer fins al crash. - Elimina gpu_boid_buffer.hpp/cpp (GpuBoidBuffer, BallComputeData, BoidParams) - Elimina kBoidComputeMSL i kBallComputeVertMSL de gpu_pipeline - Elimina boid_compute_pipeline_ i ball_compute_pipeline_ - Elimina use_gpu_boids_, boid_params_, ball_screen_uniforms_ de Engine - Elimina syncAndExitGpuBoids() i tot el compute dispatch de render() - Mode BOIDS ara usa sempre boid_manager_ (CPU, spatial hash O(N)) i renderitza via gpu_ball_buffer_ instanced (mateix path que PHYSICS) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
