feat(enemy): 追击(nav)也夹紧悬崖边缘——碰撞体前缘不越地形边缘

MoveWithSpeed(导航跟段驱动追击)原先无边缘夹紧，仅靠 nav 图，agent 按点定位
可让碰撞体前缘越出段/地形边缘约半个碰撞体宽。现加"悬崖"夹紧(WouldFallAhead，
按碰撞体前缘即时判定)，贴地生效：追击时碰撞体边缘停在地形边缘、不越界，与 Pace
一致。只夹悬崖不夹墙(墙交寻路绕行，免误夹停)；跨沟的 nav-link 跳/落不经
MoveWithSpeed(仅 IsMovingOnSegment 时写速度)，故不影响跳跃/下落过沟。

WouldBlockAhead 拆为 WouldHitWallAhead / WouldFallAhead 复用；PlayMode 校验
拆分正确(前缘朝悬崖侧 WouldFall=True)、Pace 不回归。
