## Description

Implement a checkpoint system built on top of GlobalState models to enable long-running migration tasks to persist their progress and resume from the last successful checkpoint if interrupted or failed, improving migration reliability and reducing time to recover from failures

## Acceptance Criteria

- [ ] Checkpoint system can save migration progress using GlobalState models
- [ ] Migration tasks can resume from last successful checkpoint after interruption
- [ ] System tracks migration metadata including timestamps and completion status
- [ ] Checkpoints include validation to ensure data integrity at resume points
- [ ] Migration framework integrates seamlessly with existing migration patterns
- [ ] Error handling gracefully manages checkpoint corruption scenarios
- [ ] Performance impact on migrations is minimal
- [ ] Documentation covers checkpoint usage patterns and best practices
