Step 0 of the planned vue->react migration. React 19, antd 5, i18next
+ react-i18next, typescript 5, and @vitejs/plugin-react 6 are added as
dev/runtime deps alongside the existing vue stack. Both frameworks
coexist in the build until the last entry flips.
* vite.config.js: react() plugin runs next to vue(); new manualChunks
for vendor-react / vendor-antd-react / vendor-icons-react /
vendor-i18next. Existing vue chunks unchanged.
* eslint.config.js: typescript-eslint + eslint-plugin-react-hooks
rules scoped to *.{ts,tsx}; vue config untouched for *.{js,vue}.
* tsconfig.json: strict, jsx: react-jsx, moduleResolution: bundler,
allowJs: true (lets .tsx files import the remaining .js modules
during incremental migration), @/* path alias.
* env.d.ts: Vite client types + window.X_UI_BASE_PATH typing +
SubPageData shape consumed by the subscription page.
Vite stays pinned at 8.0.13 per the existing project policy. No
existing .vue/.js source files touched in this step.
eslint-plugin-react (not -hooks) is not included because its latest
release does not yet support ESLint 10. react-hooks/purity covers
the safety-critical case; revisit when the plugin updates.
