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.
