What changed

• Bumped the abstract-node chart version from 0.1.37 to 0.1.38.
• Updated the default external node app/image version from 29.14.0 / v29.14.0 to 29.19.0 / v29.19.0.
• Added node.extraEnv so operators can append arbitrary environment variables to the external node container beyond the chart's preconfigured env vars.

Impact

Chart users can now set additional node environment variables through values without needing to fork or patch the StatefulSet template.
