stress

Upstream examples that curation keeps off the Conformance page: sweeps of a character class and variants of a form markz cuts or doesn't read, written by test/vendor.ts next to the curated file in ../, from the same pinned commit. They aren't filed or given a status. stress.test.ts only holds markz to what must hold for any input: it finishes quickly, doesn't throw, builds a valid tree, and warns over every bare URL GFM links and every footnote it reads.

• directive.md: micromark-extension-directive tests that repeat a rule already kept: the shared name, label and attribute rules again for leaf and container directives, variants that differ in one character, the content group's repeats of attribute syntax, and a directive next to a block form markz cuts (95).
• gfm-autolink-literal.md: the fixtures that sweep http:// and www. before each ASCII punctuation character, each character before a URL, and character references in a domain or path (14). Their sweep found a hang, www._.
• gfm-footnote.md: fixtures on what a footnote holds (blank lines, prefixes, nesting, continuation, constructs inside) (29).
• yaml.md: yaml-test-suite tests beyond the first example of each YAML feature (130).
