Slice 4 of #92. The XSD complex-type and identity-constraint validators move onto the validation framework, producing located results. - ComplexValidator threads a coding path through its (inherently recursive) descent, so every content-model, attribute, and simple-type violation is now a ValidationError located by path ("... at path: order/qty"). Child steps carry a sibling index only when a name repeats. - IdentityValidator returns ValidationError instead of Issue. - A new XSD rules enum wraps both as Validation<Node, XSDContext> values gated to the document root, combined by Validator<XSDContext>. XSDContext carries the type table, the identity constraints, and the root declaration. - Schema.Document.validate builds the context and runs the validator, returning [ValidationError]. XSD content-model validation is recursive by nature (a child's type depends on its position), so the rules delegate to the recursion while contributing to one error collection. Schematron is the last validator on Issue and migrates next.
