- Add `target?: string` field to `ButtonItem` interface
- Set `target: '_self'` on all locales' Try Live button configs (EN, ZH, JA)
- Bind `:target="item.target"` on the `<a>` element in HomeButton.vue
VitePress intercepts clicks on anchor tags without an explicit `target`
attribute and routes them through Vue Router, which causes a 404 for the
external https://airi.moeru.ai/ link. Setting `target="_self"` makes
the browser skip the router and perform a native navigation.
