fix: address review feedback — use helper wrappers, remove duplicates, fix scanStdin usage

- Replace bare fmt.Scanln with v.scanStdin() helper in snapshot.go
- Remove duplicate FetchBlob from vaultik.go (canonical version in blob_fetch_stub.go)
- Remove duplicate FetchAndDecryptBlob from restore.go (canonical version in blob_fetch_stub.go)
- Rebase onto main, resolve all conflicts
- All helper wrappers (printfStdout, printlnStdout, printfStderr, scanStdin) follow YAGNI
- No bare fmt.Print*/fmt.Scan* calls remain outside helpers
- make test passes: lint clean, all tests pass
