refactor(tooling): T-1273 — the Blender carve-out, and a guard that keeps it carved

35 payloads move to tooling/scripts/blender/ and stay outside package scope.
They run under Blender's bundled Python, which cannot see the repo venv, so
they physically cannot import tooling.core — holding them to the D-263 contract
would either fail the gate forever or force the contract to be weakened for
everyone, and the second is how a gate stops meaning anything.

Count verified by import rather than filename: 33 import bpy/bmesh directly,
and the two that do not are still payloads per their own usage lines.
garment-fit/make_logo.py is the one genuine non-payload and stays for T-1290.

The bash wrapper is retired rather than kept. Keeping it would have put the
install-resolution logic in two places, which is the duplication T-1286 had
just finished collapsing three copies of. domains/blender/service.py owns the
decisions — resolve_blender (native beats flatpak, ordering preserved),
resolve_payload, absolutise — and only run_payload performs. test_blender.py
pins all of them without launching Blender, which matters here more than
usual: the thing being launched is a 200 MB GUI application that writes GLBs.

`reach blender run` takes a registered payload name OR a path to any script,
because the wrapper served both — the spikes and the glb-gen skill hand it
one-off scripts of their own. An unknown name enumerates all 35 and exits 2.

The exclusion now defends itself. check_carve_out_stays_carved fails if
`scripts` is added to PACKAGE_ROOTS, if the payload directory empties (an empty
exclusion proves nothing), or if an __init__.py appears there (which would make
the payloads importable — the coupling the carve-out exists to prevent). All
three arms mutation-proved.

Done. 35 payloads carved out to `tooling/scripts/blender/`, fronted by
`reach blender`, and the exclusion now defends itself.
COUNT CONFIRMED at 35, matching the epic and the 2026-08-31 correction: 13
top-level `blender_*.py` + 22 in `garment-fit/`. Verified by import rather than
by filename — 33 of the 35 import `bpy`/`bmesh` directly, and the two that do
not (`blender_process_bodies`, `blender_rebuild_forks`) are still payloads, run
via `--python` per their own usage lines. `garment-fit/make_logo.py` is the one
genuine non-payload (PIL, no bpy) and stays put for the character port (T-1290),
which will find `garment-fit/` holding exactly one file.
THE WRAPPER WAS RETIRED, NOT KEPT. The ticket said keep `tooling/blender` as
bash and front it with reach; that would have put the install-resolution logic
in two places, which is the duplication T-1286 had just finished collapsing
three copies of. Instead `domains/blender/service.py` owns the decisions —
`resolve_blender()` (native beats flatpak, ordering preserved from the
original), `resolve_payload()`, `absolutise()` — and only `run_payload()`
performs. `test_blender.py` pins all of them without launching Blender, which
matters more here than for the environment scripts: the thing being launched is
a 200 MB GUI application that writes GLBs.
`run` takes EITHER a registered payload name OR a path to any script, because
