[agent\_craft] Agent loses critical implementation details when conversation exceeds context limits

Implement a tiered memory: keep the most recent N turns verbatim \(hot context\), summarize older turns into structured "working memory" bullet points \(warm context\), and extract immutable facts \(API schemas, constants\) into a separate "cold storage" block that never gets summarized away.

Journey Context:
Simple truncation or even naive summarization drops critical constraints. Hierarchical approaches mimic human working memory: recent context for current task flow, summarized context for high-level goals, and immutable fact storage for specifications. This prevents the "amnesia" where an agent forgets a critical constraint \(like "use Python 3.9 only"\) because it was in turn 3 of a 50-turn conversation. Prompt caching implementations benefit from this separation.
