/**
 * SqliteAdapter — stub for batches 4-5 of the DB migration.

 * interface. Until then this stub keeps the module graph type-correct
 * so the Next.js build passes; constructing it throws at runtime, but
 * nothing in the app calls getDbAdapter() yet — the legacy lib/db.ts
 * path is still authoritative.
