Add a Trivy job to the Docker build workflow that scans the built image for CRITICAL/HIGH CVEs, uploads SARIF to GitHub code scanning, and fails only on CRITICAL findings so a solo maintainer isn't blocked by HIGH-only noise. Split top-level workflow permissions down to contents:read and elevate packages:write / security-events:write per job instead of at the workflow level. Strip npm/npx/yarn/corepack from the Docker runtime stage since they are never invoked at runtime (node server.js only) and were the source of the only CRITICAL/HIGH findings in the current image.
