fix(audit): converge on the 2026-07-23 animation standard — tool sync, QuatSkin INBOX, registry corrections

From the conformance audit (ariki-game .agents/audits/animation-standard-assessment-2026-07-23.md):
- tools/: cc_retarget + mixamo_retarget re-synced from ariki-game (were stale forks
  missing --despike/--fingers/--map ual); kevin_retarget path now repo-relative;
  mirror rule documented in exchange/GUIDE.md
- INBOX/lena: add canonical Ariki_Female_QuatSkin.glb; README marks MixamoSkin superseded
- REGISTRY: tide_dance_01 flagged (no DanceType enum entry); rain_dance note corrected
  (RainDance IS in the enum); boat table notes live canoedismount1/run_to_dive; QC split
  (loop_qc pre-commit vs anim_qc post-ingest) documented
- docs/iclone-bridge.md: stub created (GUIDE referenced it but it never existed)

 # Lena character (from ariki-game)
 
 The new Lena character, exported from `ariki-game/assets/quaternius/derived-bodies/`
-(Ozan's standard-rig work, committed 2026-07-21).
+(Ozan's standard-rig work, 2026-07-21 → standardized 2026-07-23).
 
 | File | What it is |
 |---|---|
-| `Ariki_Female_MixamoSkin.glb` | **The game-ready Lena** — her mesh with Mixamo-derived weights transferred onto the Quaternius v1 skeleton, textures embedded. This is the exact body the game loads (dance bed model dropdown, combat stations, body bed). |
+| `Ariki_Female_QuatSkin.glb` | **⭐ THE canonical game body (standard 2026-07-23)** — Mixamo weights on Quaternius rest orientations, exact 65-bone UE-named contract, plays the stock clip libraries natively. Import THIS one. |
+| `Ariki_Female_MixamoSkin.glb` | **SUPERSEDED** by QuatSkin (kept for reference) — Mixamo-convention rig (no `root` bone, Mixamo leaf names); needed the now-stale msrig clip reroute. |
 | `lena_tpose_legs5_mixamo_rigged.fbx` | Mixamo-rigged T-pose FBX (legs5 variant) — the rigged source; best starting point for importing into iClone/CC or Mixamo on the PC. |
 | `lena_tpose_for_mixamo.fbx` | Unrigged T-pose mesh, the file that was uploaded to Mixamo's auto-rigger. |
 | `Lena_Body_Toned.png` / `Lena_Head_Toned.png` | Toned base-color textures (FBX files don't embed them). |
