feat(feedback): 命中/受击反馈支持固定位置与击中位置两种生成模式

DamageInfo 新增运行时字段 HitPoint：HitBox 结算时写入精确接触点
(ClosestPoint)，HurtBox.ReceiveDamage 以解析后命中点兜底盖戳，
陷阱/环境等直调路径同样可用。IFeedbackPlayer.PlayHit/PlayTakeHit
增加命中点参数，全链路（武器实例→PlayerCombat→HurtState→
EnemyFeedback）透传。各 Feedback 组件命中/受击槽位新增
FeedbackPositionMode（Fixed=反馈链编排的固定位置 /
HitPoint=传入命中点，启用位置选项的模块在该点生成），由编排
反馈链的开发者在 Inspector 按表现选择；武器命中默认 HitPoint
（火花贴点），角色级默认 Fixed（震屏/振动与位置无关）。
