jpmschweitzerandClaude Opus 5.5 26cc8de7f3 refactor(tooling): T-1290 — the character domain, and six payloads the map misfiled
`reach character {logo, strip-glb, qa, qa-analyze}` replaces make_logo.py,
glb_strip_utility_nodes.py, analyze_captures.py and the run-garment-qa bash
driver. The QA configs and method doc move beside the domain (qa_configs/,
GARMENT_QA.md), and `qa` takes a config name (`reach character qa hoodie_modern`)
or a path.

Parity, from baselines taken before anything moved:

- the logo PNG is byte-identical
- a synthetic GLB with three real utility nodes strips to identical bytes
  (the committed bodies strip 0 nodes, so they proved nothing)
- re-analyzing a cached capture set gives a byte-identical report.json and
  summary

run-garment-qa is rewritten, not wrapped (D-263). Its decisions — which config,
which Godot ($GODOT, then ~/bin/godot4, then PATH), and whether xvfb-run is
needed — are capture_plan(), pinned by tooling/test_character.py without
launching Godot. The bash exit codes are kept: 2 for a missing config, 3 for
no Godot.

The T-1271 domain map was wrong about this domain. Six of its ten files import
bpy: convert_outfit, inspect_glb, check_hair_symmetry, check_icosphere,
render_quaternius_test and test_quaternius_raw. They are Blender payloads and
joined the carve-out as blender_* (41 payloads now). The 22 existing payloads'
docstrings still cited tooling/garment-fit/ from before T-1273; fixed.

Archived, with reasons in tooling/archive/README.md:

- setup_clothing_metadata.py wrote coverage data for five garments that no
  longer exist in the 24-garment wardrobe
- wipe-bodies.sh ran raw DELETEs on systems.db

segment_reference_distribution.md moved to docs/assets/visual/.

Behaviour changes:

- The QA analyzer exited 0 whatever it found, though its own README says
  clip-through "is the real defect and it gates". qa and qa-analyze now exit 1
  on clip-through, and the remedy names --min-pixels (Wave 1/2 were accepted
  at 150). The cached peasant set has 33 failures at the default 8 px.
- glb strip re-reported the same nodes as stripped on every re-run and
  rewrote an unchanged file: it left them as orphans and then found them
  again. Only nodes still linked into the graph count now, and a first pass
  writes the same bytes as before.
