[frontier] Agent identity fragments across checkpoint restores in long-running workflows

Use LangGraph's checkpointer to store immutable 'identity nodes' that are re-read into working memory before each super-step, anchoring the agent's persona across thread restarts.

Journey Context:
When agents run for hours with checkpointing, restoring from state often loads only the recent message history, losing the original 'vibe' or specific instructions given at session start. LangGraph's checkpointer supports separate 'state' versus 'config' storage. By carving out an identity subgraph that is never summarized and always loaded first on resume, you prevent the 'zombie agent' problem where the technical capability persists but the original mission context \(e.g., 'you are a security-focused auditor'\) evaporates. This is distinct from simple system prompts; it's a persistent state channel.
