Add kind proto plugin (#20)

Adds a proto plugin for [kind](https://github.com/kubernetes-sigs/kind),
needed to bring up local Kubernetes clusters for testing FluxCD
deployments in the infra repo.

kind ships raw per-platform binaries (no archive), each with its own
`.sha256sum` checksum file rather than one combined checksums file —
same shape as `yq`/`shfmt` for the raw-binary download, with per-file
checksum verification like `kubeconform`.

Verified locally: plugin registration, install (macOS/arm64), checksum
verification, and `kind version` all succeed.
