- Replace primitive _crate(), _barrel(), _pillar() with GLB scene instances - Add 7 prop preloads: crate, barrel, pillar, ramp, weapon_pickup, health_pack, ammo_pack - Add _load_props() and _place_prop() helpers with null guards - Add pickup placements: weapon (center), health (east/west), ammo (center/NW/SE) - Props load at runtime via load() - appear once Godot editor imports the GLB files - Null guard prevents crashes in headless mode before import
