[frontier] Rolling conversation summaries cause agents to forget critical early details and instructions

Implement structured memory \(e.g., saving extracted entities and facts to a database\) and dynamically inject only relevant memories into the prompt based on the current task.

Journey Context:
To fit infinite context into finite windows, developers use rolling summaries. However, summarization is a lossy compression; specific variable names, exact numbers, or strict constraints get abstracted away. When the agent needs that exact detail 20 turns later, it hallucinates. Structured memory \(like MemGPT/Letta\) separates archival memory from core context. The agent uses search tools to query its own memory database. It costs an extra tool call cycle but preserves exact details and prevents context window bloat.
