Subject: [PATCH] Fix: kill stale tmux session as separate command, not in
 chain

tmux aborts the entire command chain when kill-session fails (no
existing session). This caused 'no current target' error on Linux.

The kill-session is now a separate exec.Command() call before
starting the tmux chain, ignoring any error.
