Chart version downgrade breaks Helm upgrade path

High Severity

Downgrading the Helm chart version from 2.0.1 to 1.0.0 breaks the upgrade path for anyone who has already deployed the 2.0.1 chart. Helm treats 1.0.0 as an older release, so helm repo update && helm upgrade will not pick it up, and existing >=2.0.0 version constraints in any dependent charts will stop matching. This effectively makes the new chart unreachable for existing users without a manual uninstall/reinstall cycle.
