[frontier] Context window overflows in long-running agent workflows causing silent failures

Implement hierarchical working memory with semantic eviction policies using importance scoring rather than FIFO truncation

Journey Context:
Most agents use simple token counting and truncate oldest messages, which loses critical tool results. Production systems now use structured memory tiers \(working vs archival\) where an LLM judges importance before eviction. This preserves tool outputs and user intent across long sessions. Alternatives like summarization chains lose granular detail; semantic eviction keeps retrievable context.
