// calls runNpm(['pack', ...]) and runNpm(['install', '-g', ...]) — if those inherit
// an unwritable HOME from the environment (common in constrained Docker hosts),
// the entire hook fails and all 6 subtests are cancelled.
//
// Fix: runNpm() must inject an explicit HOME, npm_config_cache, and
// npm_config_userconfig that point into a temp directory it owns, so that npm
// never reads from or writes to the caller's HOME.
//
// Test 3 (added in the second fix pass) verifies that isolatedNpmEnv() — the
// companion export that lets runSmoke() apply the same isolation — also redirects
// HOME away from the caller's HOME. Without this, subtests A-F of
// release-tarball-smoke.install.test.cjs still fail because runSmoke() calls
// spawnSync('npm', ...) internally and was not covered by the runNpm() fix.
