chore: reorganize imports and add Lefthook git hooks setup

- Reorder imports in kv-rocksdb and sql-spin-sqlite components for consistency
- Add Lefthook configuration for pre-commit formatting hooks
- Add lefthook-install and setup targets to justfile for streamlined development workflow
- Move setup target definition for better organization in justfile
