init option of createHead doesn't apply initial title

[innocenzi]

Environment

@unhead/vue 2.0.0-rc.2
node v23.6.0

My app is using Hybridly, but I was able to reproduce on a Vite SPA on Stackblitz.

Describe the bug

I would like to have a default titleTemplate for all my pages, such as if I don't specify a title in a page, it will use the default one. In @unhead/vue v1. I am using it like this:

// v1
const head = createHead()
head.push({
	titleTemplate: (title) => `${title ?? ''} — Jetfly Group`.replace(/^ — /, ''),
})
vue.use(head)


// v2
vue.use(createHead({
	init: [
		{ titleTemplate: (title) => `${title ?? ''} — Jetfly Group`.replace(/^ — /, '') },
	],
}))

However, in v2, this no longer works. titleTemplate is never called, unless a page calls useHead with a title property.
