/**
 * Unit tests for vite-plugin-cesium-engine
 *
 * Strategy
 * ─────────
 * The plugin is a pure function that returns a Vite Plugin object. We unit-test
 * it by:
 *   1. Mocking `node:fs` and `node:path` so nothing touches the real disk.
 *   2. Calling the plugin factory and invoking each hook directly (config,
 *      configResolved, load, resolveId, transform, transformIndexHtml,
 *      closeBundle).
 *   3. Asserting on return values and side-effects (console.warn/log calls).
 *
 * The configureServer hook is integration-level and is covered by a smoke test
 * only (verifying the middleware is registered without spinning up a real server).
