I reviewed this error with AI. Seems like the error is related to versioning with the main file and since this is a new addition, the linter is getting caught trying to compare versions. It spit out a draft fix for the github actions to more gracefully handle new chart additions:

# name: lint-test

on:
  pull_request:
    paths:
      - 'charts/**'

jobs:
  lint:
    runs-on: ubuntu-latest

        uses: actions/checkout@v4
        with:

      - name: Set Chart Name
        run: |
          CHANGED_CHART=$(ls charts | grep dns-canary || true)
          if [ -z "$CHANGED_CHART" ]; then
            echo "❌ No changes detected for dns-canary, this job may have been triggered incorrectly."
            exit 1
          fi
          echo "CHART_NAME=$CHANGED_CHART" >> $GITHUB_ENV

        run: |
          if git ls-tree -r origin/main --name-only | grep -q "charts/$CHART_NAME/Chart.yaml"; then
            echo "NEW_CHART=false" >> $GITHUB_ENV
          else
            echo "NEW_CHART=true" >> $GITHUB_ENV
          fi

        if: env.NEW_CHART == 'true'
        run: |
          echo "🔔 Detected new chart ($CHART_NAME). Skipping version bump check."
          helm lint charts/$CHART_NAME/

      - name: Helm Lint (Existing Chart Flow)
        if: env.NEW_CHART == 'false'
        run: |
          echo "🔔 Existing chart detected. Performing normal lint + version bump check."
          # Example - customize this part if your repo has special rules for version bumps
          helm lint charts/$CHART_NAME/
          # Optional - Add version comparison logic if needed for existing charts.```

Linting is failing, but I'm not sure how to troubleshoot.

Need to rename the directory to dns-canary so that it's a valid DNS name when used to create k8s resources.

Just a couple more small changes. Once we have this published, let's deploy it into the Moonswitch cluster for testing first.
