Checkov 3.3.9 binaries (built by Terrapod)

Checkov 3.3.9 binaries, built by Terrapod for the platforms its binary cache serves (#2066).

Upstream stopped publishing checkov_linux_arm64.zip at 3.3.21 (bridgecrewio/checkov#7729), which
made every security scan on an arm64 agent pool record errored. These are built from
upstream's own release tag, its committed Pipfile.lock and its committed checkov.spec,
on python:3.9-bookworm — the same recipe as its own nightly.yml, pinned to an
older glibc so the bundle runs on every runner image.

Each linux asset was executed before publication: upstream's own smoke test, plus the exact
--framework terraform_plan invocation the runner uses, asserting the graph checks fire.

Build provenance is attested — gh attestation verify <asset> --repo mattrobinsonsre/terrapod.
