Added

• Added aggregation functions: sum(), avg(), min(), max()
• Added groupBy(), having(), distinct() query support

• Added query('table').exists() chain API for efficient existence checks based on conditions without loading full records
• Added table schema TTL configuration and automatic expiration cleanup for time-based data
• Added pure memory mode (ToStore.memory()), providing ultra-high performance for scenarios like data caching, temporary computation, or diskless environments
