chore: unify Cursor rules, fix monorepo install hooks, refresh basic docs

Add root preinstall to set githooks and disable parallel vp config git lock races; merge per-app Cursor thin rules into app.mdx; keep template READMEs free of monorepo-only paths and describe basic as default English rather than English-only.

 - Prefer reusable components and hooks over copy-paste logic.
 - Keep styles token-driven using existing theme/store patterns.
 - For Ant Design styling, follow this priority: component native API (`variant`/`type`/`size`/`styles`/`classNames`) -> `theme.useToken()` with inline `style` -> `className` + external CSS.
-- Keep translations compatible with Lingui macros and catalogs.
+- Keep user-facing copy in English as plain string literals (this template has no i18n layer).

-For **LinguiJS** (English + Chinese, `.po` extract/compile, and Ant Design locale switching), use [`apps/with-lingui`](../with-lingui/).
+User-facing copy lives in components and routes as plain strings. **Default language is English**; Ant Design is wired to `en_US` in `__root.tsx`. This template does not include a locale switcher or translation catalogs—you can add your own i18n library or start from the [`with-lingui`](../with-lingui/) template for LinguiJS (en + zh).
 
 ## Extending the template
 
 - **Real backend:** Point `VITE_API_BASE_URL` in env and disable or remove MSW in `main.tsx` when you no longer need mocks.
-- **Add i18n:** Start from [`apps/with-lingui`](../with-lingui/) or port Lingui setup from that app; this `basic` tree intentionally omits it.
+- **Add i18n:** Integrate your preferred stack, or copy patterns from [`apps/with-lingui`](../with-lingui/).
