act1: FPV-комната с подарком, запиской и флешкой

3D-сцена 4×4м: стены/пол/потолок, окно (свечение), дверь, стол с пека,
кровать с одеялом, подарок-коробка на полу, отец-NPC в дверях.

Архитектура:
- FPVController (CharacterBody3D + Camera3D + RayCast3D) — mouse look,
  WASD, raycast-pickup, lock_input для катсцен.
- Interactable (StaticBody3D base) — toggle через collision_layer.
- DialogManager (autoload CanvasLayer) — субтитры snake-case, fullscreen
  записка, HUD-подсказки, prompt над крестом, await через signal.
- act1.gd — state machine: INTRO → EXPLORE_GIFT → INSIDE_GIFT →
  NOTE_READ → FATHER_FAREWELL (tween x-2.5) → SEEK_DRIVE → ENDING.

Канон-реплики из Пролог_Первый_день.md без правок:
- Отец intro + про флешку с Шиндой
- Записка «Не сожги. Пароль от Wi-Fi на холодильнике. — Бать»
- Мысли героя: «новый пека?», «бать ну ты красавчик», «Андрюхино так Андрюхино»

GL Compatibility renderer, unshaded материалы плоскими цветами под
pixel-art 640×360. Тестировано на RTX 5070 — стартует без ошибок.

main.tscn placeholder удалён, main_scene = act1_room.tscn.

Не покрыто в MVP (TBD):
- Опц. выход на кухню → холодильник → Wi-Fi пароль
- Mastermind hack-mini-game для подбора Wi-Fi
- Sfxr звуки (открытие коробки, шаги)
- Переход в Акт 2 (пока quit на финале)
