# test_ground_pickup_parity.gd —— 40250 地面拾取与掉落物 1:1 纯净无头自检套件
# 验证：
#   1. 3.0m 拾取有效距离判定
#   2. 骑马状态下 5.0m 拾取距离拓展
#   3. 就近优先拾取 (按直线距离排序)
#   4. 500ms 发包冷却节流 (s_dwNextTCPTime)
#   5. 所有权校验 (c_szOwnerName != GetName() 拦截 + cannot_pick_item 信号)
#   6. 稀有道具与高强装备垂直光柱 (Drop Light Beam)
#   7. ArrangeTextTail 防重叠标签排布
