plane(1.4): up.sh by profile -- context, registry, pool and images file from kind.toml

ops/ax/up.sh reads kube_context, registry, pools.default and the images path
with `python -m openultrasast.plane.profile --print`, writes the runner digest to
ops/k8s/profiles/kind-images.json instead of ~/.cache/.../runner-image, renders
ops/ax/workerpool.yaml.tmpl from the profile's pool (POOL_NAME/REPLICAS/CPU/
MEMORY, WORKER_IMAGE), and keeps an existing pool and an ax CLI newer than its
checkout instead of rebuilding them (ko and go install would refill several GB
of Go cache on this disk). smoke-run.sh takes the runner from `--print
images.runner` and runs the checkout's code with OUSAST_PYTHON. repin_templates
reads the JSON images file (runner key; the one-line pin still reads). `--print
images` returns the file path (the first live rerun fell over this). Templates
and the generated validation-46 Tasks re-pinned to the rebuilt image (128
lines, one digest).

Live: up.sh reran idempotently on kind in 38 s (every step kept except the
runner build); smoke-run.sh done in 24 s on the new image, facts.json 451 B,
summary.json 238 B delivered (record: benchmarks/measurements/2026-10-02-k8s-01-profile/).

Gates: pytest 2010 passed, 42 skipped, exit 0; ruff check 0; ruff format 0;
mypy 0; mkdocs build --strict 0.
