1.2.1

Added

• Prebuilt multi-arch image (linux/amd64, linux/arm64) on ghcr.io/spacecodee/spacee-herdr-bridge, with OCI labels; docker compose pull && docker compose up -d runs it, BRIDGE_VERSION pins a release. release.sh --push-image builds from the release tag in a temporary worktree and always logs out of ghcr.io afterwards.
• MIT LICENSE, SECURITY.md (threat model, how to report a vulnerability), CONTRIBUTING.md, a README rewritten as the public landing page, and a host setup guide with placeholders instead of machine-specific values. scripts/herdr-core-restart messages are now in English.
• Local release scripts (no CI): scripts/build.sh builds the frontend, embeds it, runs the checks, and produces linux/amd64 and linux/arm64 binaries with SHA256SUMS in bin/release/ plus a local Docker image; scripts/release.sh <version> updates both changelogs, tags both repos and never pushes; scripts/release.sh --push-image <version> pushes a multi-arch image to ghcr.io. The bridge has a -version flag.

Changed

• The Dockerfile cross-compiles with Go instead of emulating the target platform; compose.yaml names the GHCR image and still builds locally with --build.

The web app changes for this version are in spacee-herdr-frontend v1.2.1; its build is embedded in this binary.
