Pin actions/checkout@v6, shivammathur/setup-php@v2, actions/upload-artifact@v7 to commit SHAs across ci.yml and release.yml. Trailing `# v<MAJOR>` comments preserve Dependabot tag-tracking; weekly github-actions schedule in dependabot.yml unchanged. upload-artifact bumped from v4 to v7 during rebase (Dependabot PR #15 landed on main while this branch was open). Closes supply-chain forward-compatibility gap noted in Sapper M1 first-contact (2026-05-06).
