3.0.0-alpha.2

• A JSON body that is not an object now says The request body must be a JSON object. (key _root). Change it with the message key _root.object.
• Needs Dart 3.13 or newer.
• All dependencies updated to their latest versions.
• New: DTOs. A class with @Dto() and rule annotations (@Length, @Email, @Min, @Regex, @MaxSize, ...). dox_builder writes a const DtoSchema<T> with the checks, a converter and the JSON Schema. See the Validation guide.
• New: DtoSchema<T> with validateMap, safeValidateMap, fromMap, toMap and toJsonSchema. It is also a Schema<T>.
• New: Maybe<T> knows a missing key from null. DtoErrors for checks across fields in validate().
• New: FileTypes finds the real type of a file from its first bytes. @Image() and v.file().image() do not allow svg.
• New: MessageRequest.locale, ParseState.params. A message set on a rule is used as it is; the resolver only fills its placeholders.
• Rule has a const constructor and a final message, so a rule class works as an annotation. AsyncRule.failedItems() checks a list in one call.
• FileInput has length and head (the first bytes).
• Schema has a const constructor. The fluent schemas extend BaseSchema.
• Text length messages say "characters".
• Breaking: removed v.fromRules(), v.registerRule(), RuleRegistry, RuleDefinition, CallbackRule and all rule strings. Use a DTO, or a Rule<T> class.
