Duetto v1.2.1

Fixed

• S3 connect no longer crashes on a bad endpoint — entering an endpoint without a scheme (e.g. minio.example.ts.net) made the AWS SDK throw at client construction, which escaped the connect dialog's error handling and crashed the app. Scheme-less endpoints now default to https://, and any connect failure is surfaced as an inline dialog error instead of crashing.
