[architecture] Agent accumulates infinite low-value episodic memories, diluting the vector space and degrading retrieval quality

Implement an explicit reflection or extraction step where the LLM evaluates a conversation turn, extracts only high-signal semantic facts, and discards the raw episodic chaff before writing to long-term memory.

Journey Context:
Storing every conversational turn directly into the vector database feels like a safe lossless approach, but it creates a needle-in-a-haystack problem. Greetings, confirmations, and formatting discussions have high semantic similarity to future queries but zero informational value. The agent needs a write-time curation mechanism that distills the interaction into core facts and only persists those, preventing vector space pollution.
