Issue

The scheduled CI workflow fails its Code Lint Scan because golangci-lint reports an unchecked file.Close() return value in convert/loadConfig.

Discussion

The configuration loader deferred file.Close() without checking the returned error. This caused the errcheck linter to fail every scheduled CI run even though the other scan jobs passed. Ignoring the error could also hide a filesystem failure that occurs while closing the configuration file. When decoding and closing both fail, callers need access to both errors instead of losing either one.

Recommendation

Check the close result, return it when it is the only failure, and combine it with a decode failure using errors.Join. Add focused tests for both close-error paths.
