Configure base URL for GitHub Pages subdirectory deployment

[Copilot]

Assets are loading from root domain (https://kehwar.github.io/_nuxt/...) instead of repository subdirectory (https://kehwar.github.io/wallet/_nuxt/...), causing 404s on deployed site.

Changes

• Nuxt config: Set app.baseURL to /wallet/ in production, / in development
• PWA manifest: Update start_url to match base URL
• Service worker: Update workbox navigateFallback to match base URL

All use process.env.NODE_ENV === 'production' conditional to preserve local development workflow.

app: {
  baseURL: process.env.NODE_ENV === 'production' ? '/wallet/' : '/',
  // ...
},
pwa: {
  manifest: {
    start_url: process.env.NODE_ENV === 'production' ? '/wallet/' : '/',
    // ...
  },
  workbox: {
    navigateFallback: process.env.NODE_ENV === 'production' ? '/wallet/' : '/',
    // ...
  }
}

Generated HTML will reference /wallet/_nuxt/entry.*.css instead of /_nuxt/entry.*.css.

Original prompt

Deploy action to github pages results ok

But on opening the site I get

wallet/:1 GET https://kehwar.github.io/_nuxt/entry.Bniov9FE.css net::ERR_ABORTED 404 (Not Found)
wallet/:1 GET https://kehwar.github.io/_nuxt/CleRJAhL.js net::ERR_ABORTED 404 (Not Found)
favicon.ico:1 GET https://kehwar.github.io/favicon.ico 404 (Not Found)

and a blank page
