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).

Geometry/align/parts are a byte-copy of configs/piupiu_sb.json; everything else differs on purpose.\n\nDEFUSED 2026-07-31 (integration): export.out_dir used to point at the LIVE ariki-game/assets/quaternius/outfits/kapahaka and export.set was the real 'KapahakaSB', so a --to export run would have OVERWRITTEN the shipped Female_KapahakaSB_Legs.gltf. out_dir is now this config's own work dir and the set id is 'KapahakaSBTest', which collides with nothing and is deliberately absent from OutfitCatalog.cs (so G8 warns 'not registered' - that is the correct answer for a test set, and the run is safe to do end to end).\n\nexpect.islands is the measured truth from work/piupiu_sb_test/census.json: 1 island, 3620 verts, 7104 tris, z 5.184..11.126, x -2.228..2.517, in PRE-SCALE census units (align.scale_* 0.1 is applied later in `prepare`) - bounds are widened for tolerance, not tightened.\n\nexpect.penetration carries the contract defaults and IS EXPECTED TO FAIL at the `skin` stage: this garment is the shipped thigh-through-the-piupiu bug, and reproducing it headlessly is the point of G5. At `fit` (G5 --rest, written as qc/g3.json) the same block FAILS on a genuine 1-vert / 8.0mm rest-pose nick in 20_fit.blend - a real finding, deliberately not tuned away; set max_verts_rest: 1 here if a 1-vert rest budget is ever ruled acceptable."
