/**
 * Split `text` into citation-bearing {@link Chunk}s according to
 * {@link ChunkOptions}, dispatching on `options.type`:
 *
 * - `"recursive"` (default) — separator-aware greedy packing.
 * - `"markdown"` — heading/section-aware, then recursive within sections.
 * - `"sentence"` — packs whole sentences.
 * - `"fixed"` — back-to-back character windows.
 *
 * All strategies are character-based (tokenizer-free) and record the exact
 * `[start, end)` span of every chunk in the original text. Empty or
 * whitespace-only input yields `[]`.
 *
 * @example
 * const chunks = chunk(markdownDoc, { type: "markdown", size: 800, overlap: 120 });
 * for (const c of chunks) console.log(c.index, c.span, c.text);
