act1: реальное освещение + человекоподобный отец

ОСВЕЩЕНИЕ (главная визуальная разница):
- Все материалы переведены с unshaded на per-pixel shading
  (удалены shading_mode=0 во всех материалах act1_room+act1_kitchen).
- WorldEnvironment в обеих сценах: ambient_light_color бежевый,
  energy 0.4-0.5.
- DirectionalLight3D «солнце из окна»: Y-180 + X-30 rotation чтобы
  светило с севера в юг и вниз. light_energy 1.0, тёплый
  цвет 1,0.94,0.82. shadow_enabled=true с PSSM (GL Compatibility).
- В комнате: OmniLight3D fill-light возле окна для синего
  холодного света (свет неба из окна) — energy 0.5, голубой.
- В кухне: OmniLight3D под потолком как обычная лампа — energy
  0.6, тёплый белый, range 5м.
- Теперь мебель/стены/одеяло имеют объём с тенями.

ОТЕЦ (humanoid рig из 11 кубов вместо одного прямоугольника):
- Head (skin): голова
- Hair (dark brown): волосы сверху
- Torso (gray-blue shirt)
- ArmL/ArmR (рукава рубашки)
- HandL/HandR (skin кисти под рукавами)
- LegL/LegR (jeans dark blue)
- ShoeL/ShoeR (чёрные ботинки, чуть выпирают вперёд)
- Все материалы с roughness 0.6-0.95 для приличных бликов.
- FatherNPC.position = (1.7, 0, 0) — ноги на полу, голова на ~1.8м.
- Tween в act1.gd для exit работает как раньше (position:x).
