Routes the value and stream APIs through the ported scanner+parser (the event API already was), so PureYAML now parses entirely on the libyaml port. Adds the features needed to match and exceed the previous engine: JSON UTF-16 surrogate-pair \u escapes, bare documents after an explicit `...`, reserved-directive handling that still requires a following `---`, and a 64-level nesting bound enforced on the event stream so deeply nested input fails with nestingTooDeep instead of overflowing a recursive consumer. Parser errors are translated to the diagnostic-aware ParseError, recovering precise codes where identifiable and a readable malformed fallback otherwise; error-reporting fixtures are rebased onto the port. Canonical event conformance: 268 -> 271 of 308 (7Z25, HWV9, QT73). 393 tests pass.
