API.swift's parse(_:sax:), parse(pullingBytes:), the three events(...) overloads, and validateHTML were reached only through subsystem types, not the public wrappers. Adds direct tests: SAX callbacks in document order, an incremental byte source yielding the same tree as the string parse, all three events overloads agreeing on event count, and validateHTML flagging a duplicate id.
