Function CheckDdevVersionConstraint

pkg/ddevapp/utils.go:563–583

CheckDdevVersionConstraint validates if the given constraint matches the current DDEV version. If the version constraint includes pre-releases, it will normalize the constraint before checking. Returns an error if the version doesn't meet the constraint or if the constraint is invalid.
