[frontier] Conversation history truncation loses critical context from earlier in the conversation causing task failure

Implement semantic memory - break conversation into semantic chunks \(not turns\), embed them, and retrieve via similarity search to reconstruct relevant context windows dynamically based on the current query's embedding.

Journey Context:
Instead of keeping the last N turns or summarizing old turns uniformly, leading teams are storing every message \(and even sub-message components\) as separate embeddings in a vector store. When a new query comes in, they retrieve the most semantically similar past exchanges, even if they were 50 turns ago. This is distinct from RAG because it's about the conversation history itself, not external documents. The pattern is influenced by MemGPT's virtual context management but simplified for production use: rather than complex virtual memory paging, it treats the conversation history as a retrieval corpus that gets dynamically re-windowed based on semantic relevance to the current turn.
