/**
 * Machine flow e2e — runs against a live `pnpm dev` instance.
 *
 * The test mocks the Tauri invoke bridge in-page, then drives the React UI
 * at /machines and asserts:
 *   1. table renders the two machines returned by the mock
 *   2. opening the create dialog shows the form
 *   3. submitting the form invokes machine_create with the typed values
 *
 * Tauri mocking convention used here:
 *   window.__TAURI_INTERNALS__.invoke = (cmd, args) => mocked
 *
 * If the React UI imports a typed wrapper (e.g. `@/lib/tauri`) that bypasses
 * window.__TAURI_INTERNALS__, the affected `test()` is marked .fixme so the
 * harness fails noisily rather than silently passing — flip those once the
 * sibling agent's React lib exposes a documented mockable seam.
