Every published artifact is now cryptographically verifiable as built by
this repo's Release workflow: npm publishes carry npm provenance (OIDC,
shows the Provenance badge on npmjs.com), and the GitHub Release bundles
+ SHA256SUMS get signed build attestations via
actions/attest-build-provenance, verifiable with
`gh attestation verify <file> -R colbymchenry/codegraph`.
pack-npm.sh now writes a repository field into the generated shim and
per-platform package.jsons — npm --provenance refuses to publish without
one matching the repo — and the root package.json gains the same field.
