[frontier] Long-running agent workflows lose state on crash and cannot resume with different models

Persist not just raw state but 'resumption narratives': natural language summaries of intent, hypotheses, and blockers at each step. On resume, any agent instance reads the narrative to reconstruct context, enabling model swapping and crash recovery.

Journey Context:
Raw state snapshots \(variables\) are opaque to different models. Resumption narratives provide semantic continuity. This balances durability against flexibility, unlike opaque checkpoints which tie you to specific model versions or states.
