release: v0.2.0

[darioAnongba]

Summary

Release prep + alignment for the docs site, to tag v0.2.0 alongside the SwissKnife v0.2.0 release. Follows the deps upgrade (#8) and content alignment (#9).

Changes

• Version: 0.1.2 → 0.2.0.
• Node ≥ 24: bumped engines.node to >=24.0.0, the CI setup-node to Node 24, and the Dockerfile base image node:lts → node:24 (aligns with the dashboard/server on Node 24). Also uppercased FROM … AS … to clear the Docker FromAsCasing deprecation warning.
• Docusaurus v4 deprecation fix: moved onBrokenMarkdownLinks from the top level into markdown.hooks.onBrokenMarkdownLinks; the build no longer warns. (onBrokenLinks: 'throw' stays — only the markdown variant moved.)
• CI alignment (to match the swissknife repo): actions/checkout@v4 → v6, actions/setup-node@v4 → v6; release workflow docker/setup-qemu-action@v3 → v4, docker/setup-buildx-action@v3 → v4, docker/build-push-action@v6 → v7.
• yarn.lock: yarn dedupe consolidated duplicate transitive ranges (−350 packages, −15 MiB).

Verification

✅ yarn build passes and no longer emits the onBrokenMarkdownLinks deprecation warning. yarn install --immutable (the CI/Docker path) is consistent with the committed lockfile.

Release flow

After merge, tag v0.2.0 → release.yml builds the serve image and pushes registry.digitalocean.com/swissknife/docs:{latest, v0.2.0}.
