LANTERN feel pass (DR-052 + gap list): SoD facing, underwater feel, Bathynaut kit, walk/run gait, suit lamp + new Synty anim packs

- SoD facing: PlayerFacing = body-yaw only (move-facing / cast-turn / idle-hold); every fire
  direction re-sourced to FacingMath.ResolveAim (pre-code review blocking catch); TickWindowMath
  shared windows with Movement-skip; reticle/FX coupled to the damage direction; cursor-dash kept.
- Underwater feel: sharpness 15->6, turn 720->360, MoveSpeed 6->4.2; TuningKnob 26-28
  (0 = no-override sentinels, dev-protocol bump on DebugTuningReport); stride footsteps + silt +
  cadence floor; bubbles; underwater ambience bed + distant groans; camera drag + dev scroll zoom.
- Bathynaut kit in-engine: dome/tank/shoulder-lamp + bare head grafted (GraftSmr rigid rebase,
  RecalculateTangents); EmissiveGloamSkinned shader (Rukhanka deformation); shoulder lamp CASTS
  (warm steady spot on body yaw).
- Gait: two-ring walk/run FreeformDirectional tree (walk @0.35, run @1.0) + blended-natural
  StrideScale; additive Posture(Bank) + Lead(chest-lead) layers; idle = AnimationIdles Base;
  banking driven from facing turn rate; flat terrain (Env_SeabedKit seabed squashed - CC is planar).
- New packs: Synty AnimationIdles + AnimationSwordCombat (combat pass queued) + SyntyPropBoneTool;
  four authored clips (sway/trudge/banks/lean) + Anim_Player_Underwater.blend + suit-kit FBX.
- Validation: 411/411 EditMode green; Play smokes (server==client facing, Aim-true projectile,
  bank/stride live-sampled, lamp beam verified); pre-code + post-impl adversarial reviews applied.
