dag be96bb0050 fix(tmux): kill process group to prevent orphaned processes ...

KillSession was leaving orphaned Claude/node processes because pgrep -P
only finds direct children. Processes that reparent to init (PID 1) were
missed.

Changes:
- Kill entire process group first using kill -TERM/-KILL -<pgid>
- Add getProcessGroupID() and getProcessGroupMembers() helpers
- Update KillSessionWithProcesses, KillSessionWithProcessesExcluding,
  and KillPaneProcesses to use process group killing
- Fix EnsureSessionFresh to use KillSessionWithProcesses instead of
  basic KillSession
