Subject: [PATCH] refactor(i18n): make `defaultLocale` overridable via
 `mkDefault`

Template hard-set `en_US.UTF-8`, so a consumer setting `i18n.defaultLocale`
in the private inventory hit a conflicting-definition eval error. Wrap the
template default in `lib.mkDefault` per the overrides-are-options contract.
