/**
 * remark: render a single newline inside prose as a line break.
 *
 * CommonMark folds a lone line ending inside a paragraph into a space, so an
 * agent writing `1\n2\n3` shows "1 2 3". Chat surfaces (ChatGPT, GitHub
 * comments) keep the line, which is what message authors expect. This plugin
 * turns every line ending inside an mdast `text` node into a `break` node — the
 * same result as `remark-breaks` — while leaving code (`code` / `inlineCode`
 * carry `value`, not `text` children), raw HTML, and block structure (lists,
 * tables, blockquotes, headings, blank-line paragraphs) untouched.
 *
 * Unlike `remark-breaks` (built on `mdast-util-find-and-replace`, which drops
 * positions on the split nodes), every split text node keeps a source position.
 * Streaming tip ink (`rehypeStreamReveal`) keys fade-in on those offsets, so a
 * positionless line would render without ink and snap in at the stream tail.
 *
 * Structural local types keep the module dependency-free, like
 * `stream-reveal.ts`; the renderer casts once at the plugin seam.
