React Legacy Context Polyfill

The `create-react-context` package provides a polyfill, or more accurately, a ponyfill, for the modern React Context API (`React.createContext`) introduced in React 16.3.0. It allows applications running on older versions of React (specifically React 0.14.0, 15.0.0, and pre-16.3.0 versions of React 16) to utilize the `Provider` and `Consumer` pattern for prop drilling and state management, mimicking the official API's behavior. The current stable version is 0.3.0, and given its nature as a polyfill for a now-native feature, it is unlikely to receive significant new feature development; its release cadence is effectively dormant. Its primary differentiation was enabling forward-compatible context usage before React 16.3 became widespread, bridging the gap for applications migrating or needing modern context features in legacy environments, while explicitly *not* polyfilling other React 16+ APIs.
