Skip DOCTYPE comments/PIs and match root namespaces only as attributes
- The DOCTYPE scan now jumps over whole comments and processing instructions found outside a declaration string literal, so a quote or bracket inside them no longer leaves the scanner stuck before the root. - Root namespace repair walks the root's attributes in order, so declaration-like text inside a quoted value can no longer fill `seen` and cause the real declaration to be dropped as a duplicate. - Regression tests for both, plus linear-time cases in the isolated deadline test. - CURRENT-STATE: describe the scanner as a boundary check and leave the rest of the XML grammar to DOMParser.
