Directives apply to the document that follows, so the previous document
must be closed with an explicit '...' end marker before them. After an
implicit end, a '%YAML'/'%TAG'/reserved directive is now rejected instead
of being silently accepted. Also reject a '%YAML' version trailed directly
by '#' with no separating space ('%YAML 1.1#...'), since a comment needs
leading separation; libyaml accepts both.
This restores reject-side conformance the suite manifest recorded as
passing but the libyaml port had dropped (9HCY, EB22, MUS6/00, MUS6/01,
RHX7), and updates the two PureYAML gap-error fixtures whose rejection now
fires earlier and more precisely at the misplaced directive.
Refresh yaml-test-suite-manifest.yaml to version 3: whole-suite
conformance is 384/402 (up from the recorded 331); 53 cases still marked
as gaps now pass, none regress.
