Changes: - Added SharedMemory module for file-backed memory-mapped storage - Added MappingInfo, FileHeader, RecordState and TrackedRecord infrastructure - Replaced CSV-based serialization with binary struct serialization - Added DataStore initialization and shutdown lifecycle management - Added datastore mutex synchronization for multi-process access - Added shared-memory mapping configuration for all datastore entities - Added generic loadRecords and saveRecords template infrastructure - Added automatic datastore directory creation and .dat file storage - Updated configuration to use binary datastore files and initial capacities - Added enum underlying types for serialization compatibility - Added password masking support for login, registration and password change flows - Added Visual Studio project configuration for shared-memory components - Added datastore-owned record caches for runtime object management - Updated datastore APIs to return cached tracked-record collections by reference - Added generic cache refresh and cleanup infrastructure - Updated save operations to persist datastore caches directly - Added automatic cache cleanup during datastore destruction - Prepared datastore for multi-process shared-memory persistence
