/**
 * Runs a package's built tests: `node --test` on every `*.test.js` directly in `dist/test` (or the
 * directory given), from the package directory npm runs scripts in. A shell glob such as
 * `node --test dist/test/*.test.js` is not expanded by cmd.exe on Windows, and Node 20 does not glob
 * its own arguments; `node --test` without arguments would also run helpers such as `test/harness.js`
 * (Node 20's default patterns include every file under a `test` directory). So the list is made here.
 *
 * Every test gets a deadline (`--test-timeout`, 2 minutes unless the caller passes one) and the whole run
 * is killed after 8 minutes, so a hang on one platform fails a test (or the step) with a message
 * instead of leaving CI silent until its no-output limit kills the job.
 *
 * Usage: node ../../scripts/run-tests.mjs [dir]   (extra node --test options may follow the dir)
