The existing PPID=1 detection misses orphaned Claude processes that get
reparented to something other than init/launchd. The new --aggressive
flag cross-references Claude processes against active tmux sessions to
find ALL orphans not in any gt-* or hq-* session.
Testing shows this catches ~3x more orphans (117 vs 39 in one sample).
Usage:
gt orphans procs --aggressive # List ALL orphans
gt orphans procs kill --aggressive # Kill ALL orphans
