[frontier] Session Boundary Amnesia \(Ghost Context\)

Implement Context Genesis Markers: prepend a non-natural language delimiter \[SESSION\_GENESIS:\] at the absolute start of every session context and explicitly instruct the agent to treat this as an absolute cognitive boundary beyond which no previous context is valid.

Journey Context:
Natural language session boundaries \("Starting fresh..."\) can be semantically confused with user content or ignored. Hard UUID-based markers are unforgeable and create an explicit in-context signal of statelessness. This prevents "zombie context" where PII or instructions from previous sessions leak into new sessions despite server-side history clearing. Tradeoff: requires prompt template modification and explicit agent training/fine-tuning to recognize marker significance. Alternative: server-side state management is invisible to the model; the marker provides necessary in-context grounding.
