Summary of Changes

Hello @mattbates, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request standardizes the image pull policy across several Helm charts (cofide-agent, cofide-connect, and spiffe-enable) to IfNotPresent, which optimizes image retrieval by only pulling new images if they are not already present locally. Additionally, it includes minor formatting adjustments to improve YAML consistency and readability within these charts.

Highlights

• Image Pull Policy Update: The image.pullPolicy has been changed from Always to IfNotPresent across the cofide-agent, cofide-connect, and spiffe-enable Helm charts. This optimizes image retrieval by only pulling new images if they are not already present locally.
• YAML Formatting Consistency: Minor indentation and whitespace issues have been addressed in the cofide-agent and cofide-connect charts to improve YAML consistency and readability.
• Templating Quote Consistency: The dnsNames templating in the spiffe-enable chart has been updated to use single quotes, ensuring consistent syntax.
