Exercise 2: PM2 Restarting a Crashed Process — Possible Solution
====================================================================

SETUP
------------------------------
pm2 start ./dist/server/entry.mjs --name website-astro
pm2 save

CONFIRMATION
------------------------------
pm2 list shows website-astro running with a real process ID (PID).

Finding that PID and killing it directly, bypassing PM2 entirely:

  kill -9 <pid>

Running pm2 list again immediately afterward shows website-astro
still present, now with a new PID and its own restart count
incremented by one - PM2 detected the process died and started a
fresh instance automatically, with no manual intervention.

WHY THIS WORKS AS AN ANSWER
------------------------------
It correctly starts the server under PM2's own supervision, correctly
simulates a genuine crash by killing the process directly rather than
stopping it through PM2, and correctly confirms PM2's own automatic
restart behavior by observing the incremented restart count and new
PID.
