Add commands to find and terminate orphan Claude processes (those with
PPID=1 that survived session termination):
- gt orphans list: Show orphan Claude processes
- gt orphans kill: Kill with confirmation
- gt orphans kill -f: Force kill without confirmation
Detection excludes:
- tmux processes (may contain "claude" in args)
- Claude.app desktop application processes
- Claude Helper processes
The original `gt orphans` functionality for finding orphan git commits
is preserved.
