feat: clothing lane, character sources, and DCC bridges

Bulk import of the working lanes that were living untracked on the PC.

Content:
- characters/  Lena/male body lanes, bakes, texture work, run logs
- clothing/    garment pipeline, configs, gates, contract docs
- garments/    MD-authored garment sources (.zprj/.zpac)
- UAL-Lib/     Universal Animation Library 2 source (.blend/.fbx/.glb)
- tools/       blender_bridge, iclone_bridge, md_bridge, tailor, glm_agent
- docs/, plans/, dev/, .agents/plans/

Repo hygiene:
- .gitattributes: LFS now covers .blend, .zprj, .zpac, .obj, .npy and the
  Reallusion .iAvatar/.ccAvatar/.ccRestore containers. Without this the
  ~3.8 GB in this commit would land as raw blobs. .png/.jpg are left out
  on purpose — ~250 are already tracked raw and converting them would
  rewrite every one without shrinking history.
- .gitignore: exclude /accurig/ (~1 GB AccuRig program files, redistributable
  from Reallusion, nothing authored here) and /dev/null/ (git-lfs hook copies
  dropped by a `>/dev/null` redirect on Windows).

 # architecture/ — per-system detail
 
-This repo's pipeline is small enough that `.agents/wiki/ARCHITECTURE.md` covers
-it end to end today; nothing has grown large enough yet to need its own
-per-system doc here. Split a topic out into this folder (and link it from
-`ARCHITECTURE.md`) when it does — likely candidates as the repo grows:
+| Page | Covers |
+|---|---|
+| `clothing-lane.md` | The clothing lane end to end: reference image → Marvelous Designer authoring → `clothing/` game-ification → worn outfit in ariki-game. Read before any garment work. |
+
+`.agents/wiki/ARCHITECTURE.md` still covers the **animation** lane end to end.
+Split a further topic out into this folder (and link it from `ARCHITECTURE.md`)
+when it grows — likely candidates:
 
 - Retarget-tool internals (per-source rig mapping, bone-name conventions).
 - Loop QC/fix algorithms (pose-gap, velocity-gap, root-drift math).
