/**
 * DatabaseService for OCR Provenance MCP System
 *
 * This file serves as a facade for backwards compatibility.
 * All implementations have been modularized into src/services/storage/database/
 *
 * Provides all database operations for documents, OCR results, chunks,
 * embeddings, and provenance records.
 *
 * Security: All SQL uses parameterized queries via db.prepare() (SEC-006)
 * Performance: WAL mode, proper indexes, foreign key constraints
 * Permissions: Database files created with mode 0o600 (SEC-003)
