Detailed Description

Environment variable database management.

Manages environment variables stored in FlatImage's reserved space. Provides validation, serialization/deserialization, and key-value parsing for environment entries in 'KEY=VALUE' format. Supports reading from and writing to the binary's embedded configuration with configurable environment variable injection into the container.
