/**
 * Terminal markdown renderer for assistant replies: a pure GFM-subset
 * block/inline parser producing styled line segments the Ink renderer maps
 * to colored text. No ANSI here — the app owns color mapping, tests own the
 * structure. The subset mirrors what agent replies actually emit: headings,
 * emphasis, inline/fenced code, flat lists, blockquotes, links, rules, GFM
 * tables, and wrapped paragraphs. Unknown syntax degrades to plain text.
