PowerContext is PowerMem 2.0, the upgraded version of [PowerMem](https://www.powermem.ai/). It gives agents durable,
project-scoped context. A later session can recover a decision, outcome, current state, or next step without relying
on chat history. PowerContext includes a local Server, SQLite storage, an async Python client, a Core SDK, a CLI, and
