fix: run void prepare on install so vp check has generated route types

vite-plus 0.2.8 surfaces tsconfig errors during vp check. The root
tsconfig extends .void/tsconfig.json, which lists .void/routes.d.ts in
its files field, but that file is gitignored and only written by void
prepare. Run void prepare in the prepare script so a fresh install
(local or CI) generates it before vp check runs.

+## Built-in Commands vs Scripts
+
+`vp <name>` runs a built-in command. `vp run <name>` runs a `package.json` script or a `vite.config.ts` task. Scripts cannot overwrite built-ins, so `vp dev` and `vp run dev` may do different things. Check `package.json` and `vite.config.ts` first, and run `vp run <name>` when the project defines a script or task with that name.

 ## Review Checklist
 
 - [ ] Run `vp install` after pulling remote changes and before getting started.
