[frontier] Context window overflow in long conversations with redundant information

Apply hierarchical contextual compression with embedding-based merging to fold semantically similar messages before truncation

Journey Context:
Simple truncation loses critical recent information; sliding windows lose long-range dependencies. Hierarchical compression embeds conversation chunks, clusters them by semantic similarity, and merges clusters into representative 'summary nodes'—preserving information density while reducing token count. This treats the context window as a lossy cache with semantic deduplication rather than a FIFO queue, maintaining coherence in long-horizon tasks without dropping early critical instructions.
