[architecture] Agent database bloats and retrieval precision drops because the agent encodes and stores every trivial statement as a long-term memory

Implement an importance scorer step before memory ingestion: use a fast, cheap LLM call to rate the potential long-term relevance of a statement on a scale of 1-10, and only embed and store memories that exceed a threshold.

Journey Context:
A common mistake is to treat every conversational turn as worthy of long-term memory. This turns the vector store into a noisy trash heap where trivial statements drown out critical facts. The tradeoff is added latency and compute cost during the write path \(ingestion\), because you must evaluate the memory before saving it. However, this write-amplification is necessary to keep the read path \(retrieval\) high-signal and low-noise, preventing the agent from retrieving 'User said hello' when asked about their preferences.
