This brings the Go CLI closer to upstream behavior with global flag handling and clearer resolve failures, while adding Tidal video downloads plus initial Deezer and SoundCloud no-account flows for broader end-to-end coverage.
Write replaygain gain and peak tags from provider-specific metadata fields, then apply tagging across supported output containers with graceful cover-art fallback so non-FLAC downloads retain metadata.
Make download dedupe source-specific to prevent cross-provider ID collisions. Also correct non-remaster filtering, avoid FLAC tagging on non-FLAC files, and use album IDs for singles folder templating.
