feat(lena): v02 lane recipes + the archival full-res master

The v02 chain, which exists because bisecting the shard-eye defect proved it lives in
the hires MASTER rather than in any v02 step: the early heal chain ran whole-mesh welds
and reset custom split normals, and the eye/lash shells only read as an eye through
Tripo's authored normals. Every descendant inherits it, including the shipped body.

  48_decimate_headsafe  body/hands only, head bit-identical (feathered ramp)
  49_seams_v02          24_seams with a density-aware hip landmark — the v01 rule fired
                        at u=0.610, mid-belly, on the head-protected vert count
  50_seams_headuv       body-only unwrap; the head KEEPS its original Tripo charts.
                        SLIM collapsed the undecimated lash/brow slivers to points and
                        ANGLE_BASED packed at half v01's texel density; the face was
                        the best-mapped region of the source atlas, so it is reused
  51_reatlas_v02        31_reatlas + centroid splats for sub-texel triangles — the
                        skipped set IS the lashes, which rendered as grey glass
  52_head_transplant    the PRISTINE ORIGINAL head onto the decimated nude body
  53_rig_transfer       54_crotch_refill

55_fullres_v02.blend is pinned in .lanekeep as THE archival master: full-res nude body
+ pristine original head, crotch refill and texture despeckle applied, 883,404 v /
1,761,640 f. It supersedes 34_v04 as the lane root (34_v04's head has the shard eyes).

Also: tools/graft_hands.py, the Marvelous Designer hunter-skirt configs v1-v8, the
hunter cloth texture generator, and Mako's measurement card.

Per .agents/rules/working-files.md the per-attempt .blend files under work/lena/v02
are SCRATCH ("never committed") — the .py recipes here are the history and regenerate
any of them from the pinned master. See the ignore rule landing next.
