// Package version provides the version information for cozystack components.
//
// Version resolution order:
//  1. the COZYSTACK_VERSION environment variable, if set and non-empty;
//  2. otherwise the value baked in at build time via -ldflags:
//     go build -ldflags "-X github.com/cozystack/cozystack/pkg/version.Version=v1.0.0"
//
// The environment override lets a single image report any release name, so a
// release-candidate image can be promoted to stable by retagging alone — no
// rebuild. The deploy-time value is supplied by the installer chart
// (cozystackOperator.platformVersion) and injected as COZYSTACK_VERSION on the
// operator Deployment.
