feat (client): Added system dependencies and optimized Windows process check logic

- Explicitly included golang.org/x/sys v0.38.0 in go.mod and removed indirect references

- Optimized process liveness detection logic on Windows platforms using the golang.org/x/sys/windows package

- Used OpenProcess and GetExitCodeProcess instead of Signal detection methods to improve accuracy

- Updated command-line output and added an ASCII banner to improve user experience

- Added blank lines to the github.com/spf13/cobra package to standardize import format
