Extend homelab-audit.sh collector with zombie_parents(), swap_mb(), and
oom_events() functions so the audit identifies which process spawns zombies,
flags high swap usage, and reports recent OOM kills. Add init: true to both
Tdarr docker-compose services so tini reaps orphaned ffmpeg children, and
cap tdarr-node at 28g RAM / 30g total to prevent unbounded memory use.
Closes#30
