InMemoryProvider class

An in-memory feature flag provider for testing and local development.

This provider allows you to set, update, and remove feature flags at runtime, storing them in a simple in-memory map. It is useful for unit tests and local development scenarios where you want to quickly change flag values without external dependencies.

Whenever the flag configuration changes, a PROVIDER_CONFIGURATION_CHANGED event is emitted via the events stream.
