Report #91095

[frontier] Long-running agent tasks lose progress when interrupted by context limits or crashes

Implement explicit checkpointing with serializable agent state allowing suspension at step boundaries and resumption from last valid state using persistence layers that store thread state outside process memory

Journey Context:
Monolithic agent runs fail atomically losing hours of work; step-wise persistence with state machine integration enables human-in-the-loop approval and recovery from crashes without restarting entire workflows
