/**
 * Cross-session memory storage — public API.
 *
 * As of S90 (GH #294), persistence routes through a MemoryBackend so the
 * memory module no longer writes JSON directly. Behavior:
 *
 *   - If `.slope/slope.db` exists, SqliteMemoryBackend is used. On first
 *     open it imports any existing `.slope/memories.json` into the store
 *     and renames the JSON to `.bak` (one-time migration).
 *   - Otherwise JsonMemoryBackend is used (legacy default for repos that
 *     haven't initialized the SQLite store).
 *
 * Public API signatures are unchanged — callers (auto-memory hooks, the
 * memory CLI command, briefing) keep working without `await`.
