/**
 * Workbook Adapter — Bridge between a host workbook (implementing the
 * `WorkbookLike` / `WorksheetLike` / `CellLike` interfaces) and the
 * engine's snapshot representation.
 *
 * This is the only file in the engine pipeline that walks a live host
 * workbook; the rest of the pipeline consumes the immutable
 * `WorkbookSnapshot` this file produces.
 *
 * ## Responsibilities
 *
 * 1. `buildWorkbookSnapshot()` — walk the host workbook and produce an
 *    immutable `WorkbookSnapshot`.
 * 2. Cell value conversion — Date → serial number, rich text → string,
 *    shared formula translation, etc.
