/**
 * Forked child that evaluates a Playwright config under the env it was spawned
 * with (see resolveWebServersUnderEnv) and returns the resolved `webServer`
 * addresses along with the probe env the config left behind. A child is used
 * rather than an in-process re-evaluation because createNodes evaluates configs
 * concurrently: a shared `process.env` swap would race across them, and the
 * module cache would hand back the first evaluation.
 *
 * argv: [configFilePath (workspace-relative), workspaceRoot]. The result is
 * sent over the IPC channel as a tagged `webserver-config-result` message, or
 * `webserver-config-error` on failure.
