ci/woodpecker/push/build-ci-images Pipeline was successful
fix(ci): pin base image digests, verify tool checksums, pin claude-code version
Addresses #209. All four ci/images/*/Containerfile FROM lines were
tag-pinned only (alpine:3.21, node:22-alpine), letting the base silently
change between builds. Pin each to its current manifest-list digest.

ci/images/k8s/Containerfile downloaded talosctl, kubectl, and velero via
curl with no integrity check, and installed flux via `curl | bash`
(itself an unpinned, unverified fetch-and-execute). Replace the flux
install with a pinned-version tarball download verified against its
published sha256 checksum, same as talosctl/kubectl/velero now are.
kubectl's version was also resolved dynamically from dl.k8s.io's
stable.txt at build time instead of being pinned; add KUBECTL_VERSION.

ci/images/tofu/Containerfile's tofu.zip download gets the same
sha256 verification.

ci/images/claude/Containerfile's CLAUDE_CODE_VERSION defaulted to
`latest` and was never overridden by build-ci-images.yml, so the image
holding repo/issue-write tokens floated to whatever npm resolved at
build time. Pin it to the current release (2.1.209).

Checksums and digests verified against the respective registries/release
APIs at fix time (2026-07-14).
