JailDesigner 816bc02d9d Fase 9b: extraer ContinueSystem de GameScene
GameScene::actualitzar_continue, processar_input_continue y el
helper check_and_apply_continue_timeout (3 funciones, ~140 LOC) salen
a Systems::ContinueScreen en source/game/systems/continue_system.{hpp,cpp}.

API:
- struct Systems::ContinueScreen::Context: agrupa el estado mutable
  (state, counter, tick_timer, continues_used, game_over_timer,
  lives/score/hit_timer arrays, ships, match_config) y un callback
  get_spawn_point inyectado por GameScene.
- update(ctx, dt): avanza countdown automatico y transiciona a
  GAME_OVER si timeout.
- processInput(ctx): START revive jugador(es), THRUST/SHOOT acelera
  countdown.

Helpers privados (revivePlayer, checkAndApplyTimeout) en anonymous
namespace del .cpp para evitar contaminar el header.

GameOverState ahora con underlying type explicito (uint8_t) para
permitir forward-declaration limpia en continue_system.hpp.

dibuixar_continue y unir_jugador se quedan en GameScene (render y
gameplay normal, no parte del state machine).
