[architecture] Every memory update triggers an expensive embedding or LLM call

Batch memory writes and use lightweight extractors for high-frequency observations. Reserve LLM-based reflection for checkpoints, not every token.

Journey Context:
Memory architecture can become the dominant cost of an agent if every turn embeds every sentence and runs a reflection pass. The fix is to tier the write pipeline: raw logs append cheaply, heuristic extractors pull structured facts in batches, and LLM reflection runs only at session boundaries or when confidence is low. This mirrors how MemGPT distinguishes core memory from archival storage. The tradeoff is slightly stale memory versus real-time cost, which is almost always the right tradeoff for production.
