Module provider 

The MemoryProvider trait — the durable cross-turn memory contract.

This is the single trait every memory backend implements and every caller depends on. In Cellar that means the embedded agent runtime, the NL rule compiler, the cel_act gateway, the rule-matcher post-fire hook, the Activity / Memory tabs, and the MCP cel_remember / cel_recall / cel_forget handlers — but the trait itself is runtime-agnostic. crate::BasicMemoryProvider is the in-crate reference backend; a full storage backend (e.g. the cel-memory-sqlite crate) drops in later behind the same surface without caller churn.
