[frontier] Agents exceed context limits during long-horizon tasks and lose critical earlier context

Implement Letta's three-tier memory architecture \(core memory, archival storage, recall memory\) with automatic context swapping based on relevance algorithms

Journey Context:
Simple sliding window truncation loses crucial task history. Letta \(formerly MemGPT\) explicitly manages memory tiers: core \(always in context\), archival \(vector store for old data\), and recall \(recent events\). The system automatically retrieves relevant archival data into context when semantic similarity triggers suggest need, enabling agents to handle multi-day tasks without losing track of original goals or user preferences.
