fix(vite): match service entry chunk by facadeModuleId

🔗 Linked issue

❓ Type of change

• 🐞 Bug fix (a non-breaking change that fixes an issue)

📚 Description

when migrating nuxt to vite environment api, nitro was resolving the last chunk which was marked as an entry (in our case we were emitting a chunk which contained css for use in inlining styles).

this aims to match up the chunk to he service entry via facadeModuleId. if it fails, it falls back to the first chunk which is marked as an entry...

Note

I'm creating this PR although a lot of tests fail locally. I don't think this can be caused by this change... but just in case 🤷

📝 Walkthrough

Walkthrough

The change modifies how the service entry chunk is identified during Vite builds. Instead of emitting warnings for multiple entry points, the code now uses the environment's registered service entry to precisely match and identify the correct entry chunk by comparing facadeModuleId values.

Changes

Cohort / File(s)	Summary
Service Entry Resolution src/build/vite/plugin.ts	Refactored service entry chunk identification logic to resolve and match against the registered service entry in the current environment, replacing the previous warning-based approach with precise facadeModuleId comparison and fallback to first discovered entry chunk.
