- 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
