 * Incremental wrapper over the line-based markdown renderer, for progressive
 * TTY display of streamed AI analysis chunks.
 *
 * Buffers input until a newline completes a line, renders the completed line
 * through `renderMarkdownLine` (threading the code-fence state), and emits it.
 * Because every line is rendered by the exact same function the buffered
 * `renderMarkdown` uses, the concatenated streamed output is byte-identical
 * to `renderMarkdown(fullText)` — regardless of how the text was chunked.
 * (test-ai-stream-markdown.mjs proves this for every possible split point.)
 *
 * Trade-off: nothing prints until a line completes, so streaming is
 * line-by-line rather than character-by-character. Rewriting a partial line
 * in place would break as soon as the line wraps past the terminal width.
