MessageResolver class

Turns issue codes into messages.

Order of lookup:

1. the message set on the rule (.min(3, message: '...'))
2. messages['path.code'], like email.required or items.*.name.required
3. messages['code'], like required
4. the default English template

For i18n, extend this class and override resolve, then set MessageResolver.global or pass it to safeParse(messages: ...).
