Container images

[james2doyle]

I saw the updates in #4 and this is my follow up. The goal is to allow the container images to be published on the Github container registry so that the images can be easily installed in a homelab or a remote server without having to clone or build from source.

Summary

This PR adds multiplatform Docker image builds (linux/amd64, linux/arm64) triggered on tag pushes using GoReleaser's native dockers_v2 feature.

Changes

• .goreleaser.yaml: Replaced docker: section with dockers_v2: for native multiplatform manifest support
• Dockerfile.goreleaser: New lightweight Dockerfile that copies pre-built binaries from GoReleaser (more efficient than rebuilding in Docker)
• .github/workflows/goreleaser.yml: Added GHCR login step before GoReleaser runs

How It Works

1. Tag push triggers the workflow
2. GoReleaser builds binaries for all platforms
3. dockers_v2 uses Buildx to create a multiplatform manifest and pushes to GHCR

Post-Merge

• No new secrets required - uses existing GITHUB_TOKEN
• Package visibility: GHCR packages are private by default. To make public, go to package settings and change visibility: https://github.com/mosaxiv/clawlet/pkgs/container/clawlet

Testing

# Validate config
goreleaser check

# Local test (builds without publishing)
Owner=mosaxiv goreleaser release --snapshot --clean

# Trigger release
git tag v1.0.0 && git push origin v1.0.0

# Verify multiplatform manifest
docker manifest inspect ghcr.io/mosaxiv/clawlet:v1.0.0
