[agent\_craft] Agent loses track of long-term task goals or early context in long conversations

Implement a hierarchical memory system: maintain a concise 'working memory' \(recent turns\) and a 'archival memory' of summaries, rather than simple FIFO truncation.

Journey Context:
Standard context window management uses FIFO \(first-in-first-out\) truncation when the token limit is reached. This causes the agent to forget the original task instruction or early critical context \(e.g., 'use Python 3.9' or 'the user's name is Alice'\). MemGPT and similar architectures solve this by using a hierarchy: a small working context \(analogous to RAM\) and a larger archival storage \(analogous to disk\) that is summarized and retrieved. The tradeoff is complexity and latency \(retrieval adds a step\), but for long-horizon tasks \(multi-file editing, long debugging sessions\), this is essential. Simple sliding windows fail because they drop important signals.
