reorg(characters): ship-time folders — lena_base_v01 ships, lane moves to work/lena

REGISTRY rewritten around the central rule: a character folder is born only when a body ships to ariki-game (<character>_base_v<NN> = ship ordinal). lena_nude dissolves accordingly: - characters/female/lena_base_v01/ — SHIPPED 2026-08-10: AccuRig GLB carrier, T-pose/rig FBX + JSON, previews, frozen README - characters/work/lena/ — the live lane: recipes 01-47 (incl. new 36-47: refill/sheets/clay/despeckle/musculature/spin/AccuRig export/graft/pose QC), masters (athletic_v04 blend + textures, accurig blend), lane-history README - hires_claude/hires_work intermediates (blends, logs, probes) pruned Supporting docs: AGENTS.md, working-files rule, rig-graft plan addendum, originals README, prune_lane.py.

+# Stage 6f: fold melt in the crotch box, normal-deviation detector.
+# The mesh has only 3 boundary verts (00_welded closed the slits) — the remaining flap and
+# dotted seam lines are welded CREASES: positions locally smooth, normals kinked. Detect
+# verts whose normal deviates > ANG_THR from the 5-iter smoothed normal field, grow, melt.
