[Vapor] Using image from public directory causes error

[craigrileyuk]

Vue version

3.6.0-alpha.1

Link to minimal reproduction

https://the-sfc-playground-does-not-support-this-yet.com

Steps to reproduce

1. Run pnpm create vite vapor
2. Create a standard Vue project
3. Change Vue version to ^3.6.0-alpha.1
4. Change App.vue and HelloWorld.vue to <script setup vapor>
5. Change main.js to createVaporApp(App).mount("#app");

Inside App.vue, the Vue logo which is <img src="./assets/vue.svg" class="logo vue" alt="Vue logo" /> will work fine. However, the Vite logo which is <img src="/vite.svg" class="logo" alt="Vite logo" /> causes the following error:

TypeError: Cannot read properties of undefined (reading 'findIndex')
    at getImportsExpressionExp (/Users/username/Code/Vue3/vapor/node_modules/.pnpm/@vue+compiler-sfc@3.6.0-alpha.1/node_modules/@vue/compiler-sfc/dist/compiler-sfc.cjs.js:2152:43)

So it seems that any images from the 'public' directory cause an error.

What is expected?

For 'dev' and 'build' to work

What is actually happening?

An error is thrown when using an image src from the public directory

Any additional comments?

I'm currently investigating why this error occurs.
It seems related to the context argument passed to transformAssetUrl missing the imports property, which leads to an error in getImportsExpressionExp.
I'll update here if I find more details.
