[bug\_fix] Cannot find module './App.vue' or its corresponding type declarations. ts\(2307\)

Set \`"module": "ESNext"\` and \`"moduleResolution": "bundler"\` in \`tsconfig.json\` \(requires TypeScript 4.7\+\). Keep \`allowImportingTsExtensions\` and \`noEmit\`/\`emitDeclarationOnly\` as appropriate for the bundler workflow.

Journey Context:
You create a new Vue 3 project with Vite and \`npm create vue@latest\`. Everything works until you add a second \`.vue\` file and import it from \`main.ts\`; VS Code shows TS2307 on the \`.vue\` import. You check that \`vite-plugin-vue\` is installed and that \`shims-vue.d.ts\` exists, so the SFC shim looks correct. The real issue is that the default \`tsconfig.json\` generated by older templates still uses \`"moduleResolution": "node"\`, which cannot resolve extensionless or non-JS imports that modern bundlers handle. You change \`moduleResolution\` to \`"bundler"\`, which was introduced specifically to model bundler behavior such as resolving \`.vue\`, \`.css\`, and \`exports\` conditions, and the error disappears. The fix works because \`"bundler"\` lets TypeScript trust the same resolution rules Vite already uses at build time.
