postfx analític: nou shader + estructures chroma_min/max + scan_*

Browse Source 
- Substitueix postfx.frag per la versió analítica amb smoothstep
- PostFXUniforms 12→16 floats (64B, 4×vec4): afegeix chroma_min/max,
  scan_dark_ratio, scan_dark_floor, scan_edge_soft
- PostFXParams i PostFXPreset adopten els nous camps amb defaults d'AEE
- MSL extret a source/core/rendering/sdl3gpu/msl/{postfx_vert,postfx_frag,
  crtpi_frag}.msl.h (estil Rendering::Msl::kXxx)
- SPIR-V regenerat (postfx_frag_spv.h: 13648 bytes)
- options.cpp llegeix 'chroma' antic com compat (assigna a min i max);
  escriu els 6 presets per defecte (CRT/NTSC/CURVED/SCANLINES/SUBTLE/CRT LIVE)
  amb els valors d'aee_arcade
