fix(meta): Export isCustomModelCompatible function

The isCustomModelCompatible function was implemented in the core scripts but was not exported, making it inaccessible to other resources that depend on this library.

This commit adds the corresponding <export> tag to meta.xml, properly exposing the function and fixing potential "function not found" errors in dependent resources.
