f272bab296 feat(shaders): sistema de shaders runtime amb presets externs 
- Afegir GpuShaderPreset i ShaderManager per carregar shaders des de data/shaders/
- Implementar preset ntsc-md-rainbows (2 passos: encode + decode MAME NTSC)
- Render loop multi-pass per shaders externs (targets intermedis R16G16B16A16_FLOAT)
- cycleShader(): cicla OFF→PostFX natius→shaders externs amb tecla X
- --shader <nom> per arrancar directament amb un preset extern
- CMake auto-descubreix i compila data/shaders/**/*.vert/.frag → .spv
- HUD F1 mostra 'Shader: <nom>' quan hi ha shader extern actiu

6ffe7594ab feat(gpu): afegir suport SPIRV (Vulkan) per Linux/Windows 
- Nou: shaders/sprite.vert|frag, postfx.vert|frag, ball.vert (GLSL)
- Nou: cmake/spv_to_header.cmake — converteix .spv → uint8_t C header
- CMakeLists.txt: bloc non-Apple troba glslc, compila GLSL → SPIRV en
  build-time i genera headers embeguts a build/generated_shaders/
- gpu_context.cpp: MSL|METALLIB en Apple, SPIRV en la resta
- gpu_pipeline.cpp: createShaderSPIRV() + branques #ifdef __APPLE__
  per sprite/ball/postfx pipelines
- Corregeix crash a engine.cpp:821 (Windows/Linux) causat per pipelines
  null quan init() fallava en no trobar suport MSL

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/
