test: expand inline edge-case corpus (emphasis, code, links, escapes)

Message

Adds emphasis-edge and code-link-edge corpus docs plus goldens generated from the pristine-original parser, locking down the tricky inline semantics (unclosed/empty emphasis, nested markers, empty backticks, links without closing paren, image vs bang, escape at EOL) before further optimization.
