/**
 * rag/loaders — one adapter per format, each doing exactly one job: turn
 * bytes into text plus the positions that text came from.
 *
 * Pattern: Adapter (one per format) behind the `DocumentLoader` port.
 * Role:    rag/ layer, outermost ring. Three of the five need no dependency
 *          at all; only PDF does, and it lazy-loads a single optional peer so
 *          importing this barrel costs nothing for a consumer indexing
 *          Markdown.
 * Emits:   N/A — a loader reads a file and returns text.
 *
 * `DEFAULT_LOADERS` is the routing table `loadDocuments` uses when you pass
 * none. A loader you pass yourself is consulted FIRST, so overriding one is
 * putting yours in front rather than editing a registry.
