Merge branch 'fix/vsync-fullscreen-antialias': viewport fullscreen, VSync fallback i AA geomètric

Browse Source 
Tres fronts arreglats a la rama:

- Fullscreen: el viewport ja no depèn de zoom_factor_ (capat per max_zoom_),
  sinó que és aspect-fit de la mida física actual. Afegit
  SetWindowFullscreenMode(nullptr) i preservació del zoom_factor_ de windowed
  durant transicions.
- VSync: setVSync ara consulta SDL_WindowSupportsGPUPresentMode i fa fallback
  IMMEDIATE → MAILBOX → VSYNC quan el driver/compositor força VSync. Loggeja
  el mode efectiu.
- Antialias geomètric a les línies: edge attribute + smoothstep al fragment.
  Toggle runtime amb F5, indicador 'AA: ON/OFF' al debug overlay (F11).

#version 450
// Fragment shader para líneas vectoriales.
// Pinta el color interpolado per-vertex que viene del vertex shader.
// (Postprocesado / bloom / glow son responsabilidad de la Fase 8.)
// Fragment shader per a línies vectorials.
//
// Antialias geomètric: rebem `frag_edge_dist` interpolat (±1 als laterals del
// quad, 0 a l'eix central). Apliquem un smoothstep d'1 píxel d'amplada perquè
// el gruix nominal (els |edge_dist| < threshold) quedi totalment opac i només
// el píxel extruit als laterals faci la transició suau.
//
// La línia ja ve extruïda amb thickness + 1px a CPU; el threshold equival a
// (thickness)/(thickness+1), però no el coneixem aquí per vèrtex. En el cas
// general (línies fines), fade lineal entre 0.0 i 1.0 dóna prou bon resultat
// visualment sense necessitat d'un uniform per línia.
