Resolves the Aikido action-pinning finding (group 14426944, Linear SEC-512). stickydisk is a public, customer-consumed action whose release workflow runs with
contents: write+BUF_TOKENand force-moves thev1floating tag customers pull, so a compromised third-party action here is a supply-chain path into every consumer. All actions inbuild.yamlandrelease.ymlare now pinned to full commit SHAs with version comments that Dependabot's existing dailygithub-actionsconfig keeps updated:Pins verified against upstream refs;
bufbuild/buf-setup-action'sv1branch head is the same commit asv1.50.0, so behavior is identical to what@v1resolves today.Risk stoplight: GREEN. Config-only, no dependency or code changes; SHAs resolve to the exact commits the floating tags/refs point at today. Revert = single commit revert.
