refactor: remove redundant code and improve socket name generation

The commit refactors the code in `command_start.sh` and `linuxgsm.sh` to remove redundant code related to generating a unique tmux socket name. The code now creates a uid file if it doesn't exist, stops the running server, generates a uid using the current timestamp, and updates the socketname accordingly. This change improves the efficiency and reliability of socket name generation.
