Erik 67b51a3e6f fix(anim): implement adjust_motion — TurnLeft/SideStepLeft play backward
ROOT CAUSE FIX for missing left-side animations.

The AC client's MotionTable has NO cycles for TurnLeft (0x000E),
SideStepLeft (0x0010), or WalkBackward (0x0006). The real client
calls adjust_motion() which remaps these to their right-side
equivalents with NEGATIVE speed before looking up the cycle. Then
multiply_framerate() swaps LowFrame↔HighFrame so the animation
plays backward.

Source: ACE MotionInterp.cs:394-428, decompiled FUN_005267E0.

Changes:
- AnimationSequencer.SetCycle: adds adjust_motion block that remaps
  left→right with speed *= -1 (TurnLeft, SideStepLeft) or
  speed *= -0.65 (WalkBackward = BackwardsFactor)
- LoadAnimNode: when framerate < 0, swaps Low↔High (matching the
  decompiled multiply_framerate)
- GameWindow.UpdatePlayerAnimation: passes original animCommand to
  SetCycle (sequencer handles remapping internally), keeps legacy
  fallback for non-sequencer entities
