Release notes for version 0.3.16

Release date: 28 Jul 2026

• updated vm.namespace to resolve per-component namespace override: when appKey is set in the template context, the first key is used to look up <component>.namespaceOverride in chart values. Component-level namespace takes precedence over chart-wide namespaceOverride and global.namespaceOverride. Enables victoria-metrics-k8s-stack to deploy individual CRs into separate namespaces.
