Adds the %YAML and %TAG directive scanner, the final scanner piece. Ports fetch_directive, scan_directive, scan_directive_name, scan_version_directive_value/number, and scan_tag_directive_value, reusing the already-ported tag handle/URI scanners. Adds versionDirective and tagDirective token kinds. The libyaml scanner is now fully ported: stream, document markers, directives, block + flow structure, plain/quoted/block scalars, anchors, aliases, and tags. 319 tests, no regression.
