//! Virtual garage repository implementation for item data persistence operations.
//!
//! This module provides the data access layer for virtual garage management.
//! Each player's virtual garage is represented by six category fields:
//! - cars: JSON array of car classnames
//! - armor: JSON array of armor classnames
//! - helis: JSON array of helis classnames
//! - planes: JSON array of plane classnames
//! - naval: JSON array of naval classnames
//! - other: JSON array of other classnames
