/**
 * SqliteIntentDocVersionStore — SQLite implementation of IntentDocVersionStore.
 *
 * SPEC bilingual+lifecycle: stores immutable snapshots of INTENT.md content
 * each time it changes, enabling version history and rollback. Mirrors the
 * intent_decisions audit pattern (immutable snapshots, hash linkage).
 *
 * ERR checklist:
 * - EP-01 / ERR-001, ERR-005: DB rows treated as unknown, mapped via guards
 * - EP-03 / ERR-002: write failures throw (fail loud)
 * - rc-2: no `as` bypass — all row fields validated element-wise via isIntentDocVersionRow
