This repo is using tsc for building

tsconfig.json/compilerOptions includes "declarations": true.

I get the following error both in the workspace and during compilation:

The inferred type of 'Foo' cannot be named without a reference to '../node_modules/@effect/data/Equal'. This is likely not portable. A type annotation is necessary.

no .d.ts file is emitted.

adding "types": [ "@effect/data/Equal" ] to tsconfig.json has no effect.
