Start capturing more coverage data

[t0yv0]

Setting COVERAGE_OUTPUT_DIR on a bridged provider emits metadata about example rendering. However currently only summary metrics are captured on S3:

    - name: Upload coverage data to S3
      run: >-
        summaryName="${PROVIDER}_summary_$(date +"%Y-%m-%d_%H-%M-%S").json"

        s3FullURI="s3://${{ secrets.S3_COVERAGE_BUCKET_NAME }}/summaries/${summaryName}"

        aws s3 cp "${{ env.COVERAGE_OUTPUT_DIR }}/summary.json" "${s3FullURI}" --acl bucket-owner-full-control

Capture everything emitted but use a different S3 prefix (not ./summaries/).
