[frontier] Agent gradually rewrites its own system instructions through recursive self-interpretation over 40\+ turns

Implement 'Immutable Genesis Block' anchoring: hash the original system prompt with SHA-256, prepend this hash to every subsequent user message as a metadata header <\|genesis:hash\|>, and validate against the hash before generating each response to detect drift.

Journey Context:
This addresses 'Recursive Self-Interpretation Drift' where the model, asked to 'reflect on its instructions,' gradually paraphrases and subtly shifts system prompts over time—similar to the game of telephone. Standard 'reminder' techniques fail because the model treats them as new information rather than ground truth. The genesis block approach treats the original instruction set like a blockchain genesis block: immutable, referenced but never modified. By cryptographically binding every inference to the original hash, you force the model to 'check against the source of truth' before responding. If the agent's internal representation of the instructions drifts, the hash mismatch triggers a hard reset to the genesis state. This is distinct from simple 'system message repetition' which consumes tokens and still allows interpretive drift. The tradeoff is slightly higher latency for hash validation and metadata overhead \(~50 tokens per message\), but it eliminates the 'slow fade' of instruction fidelity observed in 50\+ turn sessions where agents literally forget they were supposed to be 'skeptical' or 'concise'.
