[frontier] Agent context windows filling up with redundant history or hitting token limits during long sessions

Implement Diff-Based Context Management where agents exchange state deltas \(patches\) rather than full snapshots, and use hierarchical summarization with re-ingestion checkpoints.

Journey Context:
Developers initially truncate history or use simple summarization, losing critical details or tool outputs. They try RAG on conversation history but latency spikes. The fix treats agent memory like a git repository: each turn generates a diff of beliefs/state, and receivers apply the patch. For long contexts, a 'rebase' occurs where old diffs are collapsed into compressed embeddings. Tradeoff: requires deterministic diff generation and patch conflict resolution. Alternative of naive truncation loses tool result history that the LLM needs for subsequent calls.
