EnvironmentGetter creates a normalized lookup from the current environment variables at initialization time and provides simple data access without validation. Per the OpenTelemetry specification, environment variables are treated as immutable within a process. For environments where context-carrying environment variables change between logical requests (e.g., AWS Lambda's _X_AMZN_TRACE_ID), create a new EnvironmentGetter instance at the start of each request.
