Root Swift package mirroring PureYAML's structure, rules, and verification gates. Includes the XML node model (Node, Element, Attribute, QualifiedName), a working emitter (Serializer) with escaping and pretty/compact options, and structural validation. The parser surface is stable; parse() raises notImplemented until the scanner lands, pinned by a test. - dependency-free, namespaced under PureXML - portability and style gates carried over (style, namespacing, forbidden patterns, swiftformat, swiftlint, linux, wasm, windows CI) - 11 tests passing
