fix(tmux): Use exact matching for HasSession to prevent prefix matches

Browse Source 
tmux has-session -t does prefix matching by default, so "gt-deacon-boot"
would match when checking for "gt-deacon". This caused gt start to think
the Deacon was running when only a stale gt-deacon-boot session existed.

Using "=" prefix forces exact matching in tmux.
