[architecture] Agent forgets established facts because it only searches episodic memory

Split agent memory into two distinct systems: Episodic \(timestamped interaction logs\) and Semantic \(extracted, timeless facts about the user or environment\). Query semantic memory for preferences and rules; query episodic for 'what happened yesterday'.

Journey Context:
Storing everything as episodic chunks \('User said they like dark mode on Tuesday'\) makes retrieving core preferences slow and dependent on phrasing. Conversely, storing only semantic facts loses the narrative context of why a decision was made. The tradeoff is the architectural overhead of maintaining dual memory streams and keeping them synchronized vs. the high fidelity of matching the right memory type to the right query type.
