 * Split Markdown into stable, heading-aware chunks. Each chunk carries:
 * - headingPath: full breadcrumb from root (e.g. ["API", "Endpoints", "GET /users"])
 * - depth: heading depth of nearest parent (0 for preamble before first heading)
 * - parentHeading: direct parent heading text
 * - frontmatter: document metadata for context
 *
 * @param relativePath - Project-root-relative POSIX source path.
 * @param content - Raw Markdown content.
 * @param options - Optional chunk sizing controls.
 * @returns Deterministic list of chunks in source order with heading context.
