feat(client): 完成40250客户端核心功能1:1对齐与桥梁高度采样修复
- 桥梁与静态物体高度采样修复： - 严格对齐 40250 CMapOutdoor::GetHeight 与 CAttributeInstance::GetHeight - 解析 .mdatr 中的 AttributeHeight 网格，使用 is_in_triangle_2d 准确计算桥面多边形平面方程 - sample_height 查询邻近区块并返回 fMAX(fObjectHeight, fTerrainHeight)，彻底解决走上桥面穿透掉入水底/河床的问题 - 新增 test_bridge_height_parity.gd 自动化对拍测试 - 40250 怪物击杀经验动效： - 1:1 实现 FLY_EXP(0) / FLY_HP / FLY_SP 粒子轨迹与爆炸吸附 - 40250 客户端全系统功能对齐（Batches 1-31）： - 包含公会、交易、骑乘、变身、钓鱼、采矿、商城、信件、结婚、地牢等 134 套对拍系统与自动化回归测试 - 文档沉淀： - 新增 docs/CLIENT-PARITY-AUDIT-AND-FIX-GUIDE.md 客户端对拍缺陷发现与修复工程指南
