Can't make it work with Vike

### Describe the bug

Hi, I'm a maintainer of [Vike](https://vike.dev) and we're trying to make Histoire work with Vike, but without success so far. It seems there are some issues on Histoire's side?

Reproduction: https://github.com/brillout/vike-histoire-build-minimal-reproduction.

Note that the reproduction patches Vike to remove its `output.entryFileNames` usage. Thus the following issue doesn't seem to be caused by Vike:

> Invalid substitution "/home/rom/tmp/vike-histoire-build-minimal-reproduction/node_modules/.pnpm/@histoire_app@1.0.0-alpha.2_vite@6.3.5_@types_node@20.19.9_jiti@2.4.2_tsx@4.20.3_/node_modules/@histoire/app/dist/bundle-main.js" for placeholder "[name]" in "output.entryFileNames" pattern, can be neither absolute nor relative path.
