feat: primary artist only folders, fix notifications v20, fix SAF duplicate dirs

- Add 'Use Primary Artist Only' setting to strip featured artists from folder names
- Fix flutter_local_notifications v20 breaking changes (positional params)
- Fix SAF duplicate folder bug: synchronized ensureDocumentDir to prevent race condition creating empty folders with (1), (2) suffixes during concurrent downloads
