Handle destroy events in up monitor

[ousamabenyounes]

What I did
Handle container destroy events in the attached up monitor so docker compose up can finish when an externally stopped project removes a container that never emitted a die event.

The monitor still uses die for exit status and restart detection; destroy only removes the container from the tracked set so the monitor can terminate when the project is gone.
