Database schema from multiple layers doesn't get merged on build output

[TheBITLINK]

Describe the bug
When building a multi-layer project, the @nuxthub/db/schema package generated inside .output/server only contains schemas from a single layer.

As a workaround, I added this to my Dockerfile to copy the module from the main node_modules (outside .output), which is correctly merged:

COPY --from=build /app/node_modules/@nuxthub/db/ ./server/node_modules/@nuxthub/db/

Steps to reproduce
Steps to reproduce the behavior:

1. Create a new Nuxt layer inside the layers directory
2. Define a database schema inside the layer
3. Define another database schema outside the layer
4. Run nuxt build
5. Check the contents of .output/server/node_modules/@nuxthub/db/schema.mjs

Expected behavior
The schema.mjs file should contain the schemas from both layers, just like the one outside the .output directory.

Current behavior
The schema.mjs inside .output only contains schemas from a single layer

Could you share a minimal reproduction for this?

I tried reproducing from the steps, but I could not get the exact reported behavior yet. To narrow this down, it would help a lot if you could share either:

• a minimal repo, or
• the exact project shape and build setup

Useful details:

cat nuxt.config.ts
find layers -maxdepth 4 -type f | sort
cat node_modules/@nuxthub/db/schema.mjs
cat .output/server/node_modules/@nuxthub/db/schema.mjs

Also helpful:

• exact @nuxthub/core version
• exact build command
• deployment target / Nitro preset
• whether the layer is wired via extends or just placed under local layers/

If you can share that, I can try to reproduce the exact failure and put together a proper fix. Thank you :)
