Documented steps
npm start runs prestart -> start -> poststart; if no start script exists and server.js is at the package root, start defaults to node server.js (pre/post still run).
npm test runs pretest -> test -> posttest.
npm restart runs prerestart -> restart -> postrestart when a restart script exists; otherwise it falls back to running stop then start (each with their pre/post iterations).
npm stop runs prestop -> stop -> poststop.

Known gotchas
These defaults mean a bare node server.js runs even without an explicit start script.
pre/post hooks fire for the default scripts too, so a failing pretest blocks the default test.
npm restart without a restart script effectively runs the full stop + start chains.
