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).

# Stage 12: membrane-heal the garment dig-in lines (waistband ledge, leg-hem creases,
|
||||
# belly/underbust dashes). These are DENTS the briefs/bra pressed into the body — the briefs
|
||||
# zone's 1x anatomy field kept them, and Taubin/melting preserves exactly this mid-frequency
|
||||
# shape. Fix = the proven pattern: narrow bands along the crease curves (mid-freq roughness
|
||||
# detector + mapped slit seams), rim-anchored bi-harmonic membrane across them.
