+/**
+ * @vitest-environment node
+ *
+ * Real end-to-end tests for Studio's site-management operations: renaming a
+ * site, changing its PHP version, updating the WordPress site title, and
+ * deleting a site (with and without removing its files). Unlike the unit
+ * suites that mock the daemon and config layer, this spawns the built CLI and
+ * asserts the real persisted state in cli.json and on disk.
+ *
+ * Requires the CLI to be built first (`npm run cli:build`); the suite skips
+ * itself otherwise. Tagged `e2e` so it runs in the slower (release/manual)
+ * suite rather than on every PR — run with `npm test -- --tagsFilter='e2e'`.
