Fase 8a+b: paleta semantica de color por entidad

Browse Source 
Cada entity declara su color de linea via parametro opcional. Cuando
alpha==0 el pipeline cae al color global del oscilador (compatibilidad
con el comportamiento anterior).

Defaults::Palette (defaults.hpp):
- SHIP        = blanco neutro
- BULLET      = verde laser
- PENTAGON    = azul "esquivador"
- QUADRAT     = rojo "tank"
- MOLINILLO   = magenta agresivo

Pipeline:
- linea(): parametro SDL_Color color (default {0,0,0,0}). En .cpp,
  fuente del color = color.a>0 ? color : g_current_line_color.
- render_shape(): parametro SDL_Color color que propaga a cada linea
  del shape.
- Debris: campo color en la struct; explode() recibe SDL_Color color
  y lo guarda en cada fragment; draw() lo pasa a linea().

Aplicacion:
- Ship::draw -> Palette::SHIP.
- Bullet::draw -> Palette::BULLET.
- Enemy::draw -> Palette::{PENTAGON,QUADRAT,MOLINILLO} segun type_.
- CollisionSystem detectBulletEnemy: debris hereda color del enemy.
- GameScene::tocado: debris hereda Palette::SHIP.

Smoke test xvfb OK.
