[frontier] Agent loses continuity when user switches between parallel task branches

Implement 'Episodic Checkpointing' using LangGraph's persistence layer: at each branch point \(e.g., 'explore security fix' vs 'explore performance optimization'\), save the full state \(messages, config\). When resuming a branch, prepend a 'memory injection' block: 'Resuming Branch-A \(Security\). Active constraints: \[list\]. Constraints from Branch-B are SUSPENDED.'

Journey Context:
Modern agents use branching workflows \(e.g., exploring multiple solutions\), but context windows linearize these, causing 'identity fragmentation' where the agent mixes constraints from parallel threads \(applying performance rules to security tasks\). Standard RAG doesn't track session branching. LangGraph's checkpointer allows true state branching. The 'memory injection' explicitly scopes the active identity and constraints, preventing cross-branch contamination. This mimics git branch switching for agent cognition.
