[architecture] Agent 'forgets' across sessions because memory lives only in-process

Persist memory from day one: thread-scoped checkpoints for short-term context and a namespaced key-value/document store for long-term facts; reload both on startup.

Journey Context:
A demo with a global list works until the container restarts. Cross-session memory changes your data model and retrieval scoping. LangGraph separates short-term memory \(checkpointer \+ thread\_id\) from long-term memory \(Store \+ namespace\). Treating persistence as an afterthought means identity, scoping, and migration all become retrofit problems.
