fix: unwrap <p> from list items so screen readers read bullets correctly

Loose markdown lists (blank lines between items) caused marked to wrap
each item in <p> tags, making screen readers announce a paragraph break
before reading the bullet text. Added a listitem renderer that strips the
wrapping <p> when an item contains a single paragraph.
