Slice 1 of #94 (editor integration). The keystone: a located validation finding can now be mapped back to a source range. - TreeNode gains a sourceRange (start/end Mark); SourceRange is a half-open span. - PureXML.readTree builds a mutable, parent-aware, best-effort tree whose every node carries its span (an element from the < of its start tag to past its end tag; leaves over the text they consumed). Never throws, recovers in place, returns located diagnostics. - TreeNode.node(at:) navigates a validation coding path to its node using the same canonical convention the validators build paths with (a sibling index only when a name repeats), and sourceRange(at:) returns the span. So Document.validate's ValidationError.codingPath resolves to characters in the document. Tests prove the spans, the navigation, the end-to-end bridge (an XSD finding to a source range), and that ranged reading of invalid input never crashes.
