Auto-accessor syntax is not transpiled

### Describe the bug

I created a new project with vp create using all the defaults

```ts
class Foo {
accessor x = 3;
}
```

does not transpile properly causing an "Unexpected identifier 'x'" error in the browser.

I've tried various target="es2025" (and older) configs in both tsconfig, vite.config.ts build target, and build.rolldown.transform.target etc. and have been unable to get this to transpile properly.

Note, that in the tsgo playground, setting the target in tsconfig is enough to work.
