[frontier] Agent tasks fail mid-execution and must restart from scratch wasting tokens and time on long-horizon tasks

Implement state checkpointing - treat agent execution as a state machine with explicit save points using persistence layers \(like LangGraph's checkpointer or Temporal\), allowing pause/resume/migration across sessions and automatic recovery from crashes.

Journey Context:
For long-running agent tasks \(multi-step coding, research, data processing\), teams are adopting patterns from distributed systems: explicit checkpointing of the agent's state \(memory, tool results, plan state, node position in a graph\) to persistent storage at key milestones. If the process crashes or needs to be migrated, it resumes from the last checkpoint, not the beginning. This is emerging from LangGraph's persistence features but applies broadly: agents are no longer expected to complete in a single request/response cycle but are treated as long-running processes that can survive pod restarts, be paused for human review, or migrated to different compute environments mid-execution.
