 * In-memory implementation of SkillSyncStateStore.

 * - Development and testing
 * - Single-instance deployments where persistence isn't required
 * - Stateless sync operations (re-sync on each startup)
 *
 * Note: State is lost when the process exits.
 *
 * @example
 * ```typescript
 * const store = new MemorySyncStateStore();
 *
 * // Save state
 * await store.save({ version: 1, lastFullSync: Date.now(), entries: new Map() });
 *
 * // Load state
 * const state = await store.load();
 * ```
