Greptile Summary

Pinned uv_version to 0.9.9 in the helm/chart-testing-action setup step to standardize the uv version across GitHub Actions workflows and prevent rate-limiting issues during CI runs.

• Added explicit uv_version: "0.9.9" parameter to the chart-testing-action step
• Uses a custom patch from feat: uv_version to pin uv helm/chart-testing-action#194 (commit 8958a6ac)
• Improved YAML formatting consistency (standardized spacing and comment placement)
• Aligns with version already used in other workflows like deployment.yml

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is straightforward and low-risk: it pins the uv version to prevent rate-limiting issues, which is a defensive operational improvement. The version 0.9.9 is already used successfully in other workflows. The formatting changes improve consistency without affecting functionality. No code logic or security concerns are introduced.
• No files require special attention
