[architecture] Agent storing raw tool outputs and conversational filler into long-term memory

Implement a memory consolidation step: before writing to the long-term vector store, use a smaller, cheaper LLM call to extract discrete, self-contained semantic facts \(triplets or concise statements\) from the raw interaction, discarding procedural noise and conversational pleasantries.

Journey Context:
Naive agents dump the entire text of tool outputs or user chit-chat into the vector DB. This quickly pollutes the embedding space with high-dimensional noise, making future retrievals return garbage \(e.g., retrieving a JSON blob instead of the fact extracted from it\). Alternatives include storing everything and relying on the LLM to sort it out \(fails at scale due to context limits\), or rule-based extraction \(brittle\). LLM-based consolidation before storage is the right call because it ensures embeddings are generated from dense semantic meaning, drastically improving signal-to-noise ratio on retrieval.
