Nitro `scanModules` returns every files

[Barbapapazes]

Environment

nitropack-nightly@3.0.0-beta-28665895.e727afda-nitro-nightly-mirror

Reproduction

1. Create the dir modules
2. Add the file log/index.ts and log/runtime/routes/log.ts
3. Inspect the return of https://github.com/unjs/nitro/blob/d20ffcbd16fc4003b774445e1a01e698c2bb078a/src/core/scan.ts#L44

Describe the bug

You'll see that the return will have both the index.ts file which define the module and the log.ts file which define an event handler. This makes the local modules system unusable.

Like Nuxt, this could be nice to only scan two patters (https://nuxt.com/docs/guide/directory-structure/modules#:~:text=The%20auto%2Dregistered,modules/*.ts)

The auto-registered files patterns are:

• modules/*/index.ts
• modules/*.ts
