3.1.0

Fixed

• @MugshotLocales did not infer right-to-left layout from Android's BCP 47 locale qualifiers.
  The language subtag was read as everything before the first -, so a b+-prefixed qualifier
  such as b+ar+u+nu+arab was never matched against the right-to-left languages and rendered
  left to right. That form matters because it is the only way to pin a locale's numbering system:
  without it, digit shapes in formatted strings come from the host JDK's CLDR data and change
  between JDK releases, so the same preview yields different goldens on different JDKs.
