Mihaela Mihaljevic 43f82312e6 feat(parser): resolve XML namespaces at the start-element boundary
Add namespace resolution following the XML Namespaces rules, reimplemented in
Swift from libxml2's SAX2 model; no upstream code copied.

- QualifiedName gains an optional resolved namespaceURI (nil for names built
  directly or in no namespace), with a resolved(namespaceURI:) helper.
- NamespaceContext maintains a scope stack of xmlns bindings as elements open
  and close, resolving element and attribute names against it.
- A default namespace applies to unprefixed element names but never to
  attributes; the xml prefix is built in; xmlns declarations are preserved as
  attributes so documents round-trip; an unbound prefix raises
  ParseError.undefinedNamespacePrefix. End-tag matching stays lexical.
- Namespace-free documents are unchanged (URIs remain nil).
- 7 namespace tests; 39 total.
