Summary

Implements PowerMemMiddleware (packages/powermem-langchain/src/powermem_langchain/middleware.py) to load relevant memories into the agent's system prompt before model calls and persist user/assistant interactions after responses.

Solution Description

• Added constructor, before/abefore_agent, after_agent, wrap/awrap_model_call, and helpers.
• Injects "powermem_context" into the system message; writes interactions via memory.add.
• Swallows memory.search errors so agents remain available if memory fails.
