Replace all structuredClone patterns with clone() utility

- Replace structuredClone($state.snapshot(x)) with clone(x)
- Replace structuredClone(stateSnapshot(x)) with clone(x)
- Replace structuredClone(x) with clone(x)
- Add clone import to 40+ files
- Remove unused stateSnapshot imports
- Fix syntax errors and import conflicts

Total: 101 structuredClone patterns replaced across codebase
