Security Fixes:
- Fix critical data loss risk in restore_checkpoint (TRUNCATE without rollback)
- Add table dependency tracking with topological sort
- Implement auto-backup before restore for safety
- Add table-level locks during restore (EXCLUSIVE MODE)
- Single transaction for atomic operations
Performance Optimization:
- Replace row-by-row insert with batch insert (executemany)

- Add configurable batch_size parameter (100-10000 rows)
- Add performance monitoring and timing statistics
- Support for skipping auto-backup for speed
Logging Enhancement:
- Detailed real-time logging for all checkpoint operations
- Progress tracking: per table, per batch, per 100 rows
- Time statistics for each table and total operation
- Structured log messages with clear identifiers
- Configured immediate stdout output without buffering
Documentation:
- Updated CLAUDE.md with improved guidelines
