PlayerMovement：新增 _facingLocked 字段 + LockFacing(bool) 方法；UpdateFacing() 锁定时直接返回 WallSlideState：OnStateEnter 调用 LockFacing(true) + FlipFacing(_wallDir)；OnStateExit 调用 LockFacing(false) 解锁 WallJumpState：OnStateEnter 保险性再调一次 LockFacing(false)；WallJumpAway/Toward 同步写入 _inputVelocityX，确保解锁后 UpdateFacing 朝向正确（背墙跳 = 离墙方向，对墙跳 = 朝墙方向）
