Lint: rename públicos al inglés + refactor cognitive-complexity + unused-includes

Identifier-naming: rename de métodos públicos y cross-file al inglés
(camelBack), traducción de campos y locales en el proceso (TitleShip,
StageManager, SpawnController, ShipAnimator, helpers de PlayArea, etc.).

Refactor por cognitive-complexity (>25): GameScene::draw (59→3) con 9
helpers de estado, PhysicsWorld::resolveBodyCollisions (35→5) extrayendo
resolveBodyPair, Options::load{Window,Physics,Audio}ConfigFromYaml
(32/49/57→5/2/3) con templates readField, TitleScene::update (68→4) con
5 sub-pasos por estado + handleSkipInput/handleStartInput +
triggerExitForJoinedPlayers, DebrisManager::explode (39→3) con
extractSegments/spawnDebris/applyAngularVelocity/applyVisualRotation.

use-anyofallof: bucles → std::ranges::any_of/all_of en Input,
ShipAnimator y SpawnController.

readability-static-accessed-through-instance: Director::run y
VectorText::getTextWidth/Height invocados por clase.

readability-convert-member-functions-to-static: ResourcePack::decryptData.

unused-includes: eliminación de <utility>, <cstdint>, <vector>,
<iostream>, defaults.hpp y otros no usados directamente en headers y
unidades de traducción. Restablecido core/defaults.hpp en title_scene.cpp
(falsa "unused" del header).

Bug fix: eliminado isActive() duplicado en Bullet (redeclaración tras
rename de esta_activa→isActive que chocaba con el override de Entity).
