saphidandClaude Opus 5.5 70897cfd1d Android launcher: stop an orphaned container instead of refusing Play; keep the lock out of Lepton's tree 
Once flock is held no launcher owns a running container (a SIGKILLed launcher
left it), so it is stopped and the launch continues. fd 9 is closed for the
Lepton child so it can't keep the lock held.
