Greptile Summary

Automated appVersion bump from 0.47.0 to 0.48.0 in the request-node Helm chart, generated by the create-pull-request GitHub Action.

• Bumps appVersion in charts/request-node/Chart.yaml to track the latest request-node Docker image tag (0.48.0)
• The chart version (0.9.0) is unchanged, consistent with the established pattern for automated app version bumps in this repository
• No template, values, or other chart changes are included

Confidence Score: 5/5

• This PR is safe to merge — it is a minimal, automated one-line version bump with no functional chart changes.
• The change is a single-line bump of appVersion from 0.47.0 to 0.48.0, following the exact same pattern as dozens of previous automated PRs. No templates, values, or other files are modified. The image tag referenced by appVersion is consumed via .Chart.AppVersion in the StatefulSet template only when nodeImage.tag is not explicitly set, which is the expected behavior.
• No files require special attention.
