d2e7f2ff86 refactor(gpu): eliminar GPU compute boids (prevé crash macOS) 
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)

badf92420b feat(engine): PostFX cycle + fixes de reinicialització i overflow 
- Afegir handlePostFXCycle() amb 5 presets (vinyeta/scanlines/cromàtica/complet/off)
  i tecla X per ciclar-los (input_handler + engine.hpp)
- Augmentar MAX_SPRITES de 65536 a 200000 i afegir guard d'overflow a pushQuad()
- Netejar textures/objectes UI abans de reinicialitzar (AppLogo::initialize,
  UIManager::initialize) per evitar leaks en toggleRealFullscreen

af0276255e feat(postfx): afegir push constants i efectes chromatic aberration + scanlines 
- PostFXUniforms struct (vignette_strength, chroma_strength, scanline_strength, time)
- Shader MSL actualitzat: aberració cromàtica RGB + scanlines sin-wave + vinyeta paramètrica
- Pipeline postfx declara num_uniform_buffers=1 (buffer(0) en MSL)
- Engine acumula temps i fa SDL_PushGPUFragmentUniformData cada frame
- Valors per defecte: vignette=1.5, chroma=0, scanlines=0 (comportament idèntic a l'anterior)

00a5875c92 feat(gpu): migrar a SDL3_GPU amb 2-pass rendering i post-processat 
- Infraestructura GPU: GpuContext, GpuPipeline, GpuSpriteBatch, GpuTexture
- Engine::render() migrat a 2-pass: sprites → offscreen R8G8B8A8 → swapchain + vignette
- UI/text via software renderer (SDL3_ttf) + upload com a textura overlay GPU
- CMakeLists.txt actualitzat per incloure subsistema gpu/
