- Native runner per platform (ubuntu-24.04 / ubuntu-24.04-arm), push-by-digest, manifest fused in a follow-up merge job.
- Per-platform buildcache scopes to avoid cross-arch collisions.
- SHA-pinned third-party actions (build.yaml + ci.yaml).
- Merge gate uses !cancelled() && needs.build.result == 'success' so workflow_dispatch doesn't leave orphan by-digest blobs.
- type=sha forced on so workflow_dispatch from non-default branches still yields a populated meta.outputs.version for Inspect.
- Dependabot config (github-actions, monthly, grouped) added.

Pull request overview
Updates the GitHub Actions pipelines to publish a multi-architecture Docker image to GHCR (linux/amd64 + linux/arm64) using per-arch native runners, digest-based pushes, and a follow-up manifest merge job, while also tightening workflow supply-chain hygiene.
Changes:
- Convert Docker publishing workflow to a per-platform matrix build that pushes by digest and merges into a multi-arch manifest in a dependent job.
- SHA-pin GitHub Actions used in CI/build workflows.
- Add Dependabot configuration for monthly grouped GitHub Actions updates.
