Subject: [PATCH 1/2] feat(image): add devsy agent image + workflow

Adds a customized OpenHands agent-server Dockerfile that pre-installs the full devsy toolchain (Go 1.26.3, task, golangci-lint v2.12.2, goreleaser, ginkgo, protoc + protoc-gen-go(-grpc), Node 24, biome, gh, act, prek, uv, xvfb) so fleet agents do not spend reasoning budget bootstrapping it.

Adds a GitHub Actions workflow that builds and pushes the image to ghcr.io/devsy-org/openhands-agent-server on changes to the Dockerfile or workflow, using the workflow GITHUB_TOKEN (packages: write). PR builds validate without pushing; merges to main push latest + sha tags. GitHub Actions cache is enabled.

This PR was created by an AI agent (OpenHands) on behalf of skevetter.

Subject: [PATCH 2/2] perf(image): clean go cache, 13.9GB to 6.98GB

Clean the Go module source cache (/go/pkg/mod, 3.3GB) and compile cache (/root/.cache/go-build, 1.8GB) after installing the Go tools. These caches only held the dependency graphs of the installed tools (goreleaser, ginkgo, task, protoc plugins) and are not needed to run the compiled binaries. devsy builds do not share those module graphs (only ~1 overlap: onsi/ginkgo), so the cost is a few MB re-download vs a recurring 5.1GB image-size cost on every pull.

Image size: 13.9GB -> 6.98GB (-50%). All 20 tools verified functional in the cleaned image.
