Adding an unregistered package to our Application Project causes `has no known versions` during `Pkg.build` resolution.

[NHDaly]

We have an Application Project mono-repo, with many separate subpackages.

Our Project.toml and Manifest.toml are attached here:
Project_and_Manifest.zip

We are running on julia 1.10.

When adding an unregistered package, we see the following error during the Pkg.build step:

(RAICode) pkg> add https://github.com/RelationalAI/logical-query-protocol:sdks/julia/LogicalQueryProtocol.jl

# ^ but this didn't work.

This seems to happen for any unregistered dependency; the LogicalQueryProtocol.jl package is just the one we're currently trying to work through. Adding a registered dependency by URL works okay. But adding an unregistered dep does not.

One possible related issue is that we have a lot of subpackages which point to the same Manifest.toml through their manifest="" field. All of those subpackages are dev'd into the project.

Thanks!

Just checking that you're not missing a custom registry?

Warning: Could not use exact versions of packages in manifest, re-resolving

I don't really see why that would happen for Pkg.build. My guess is that something with the manifest = feature is not properly hooked up, but that's just a guess.

The attached project/manifest here is not very helpful since it refers to packages within a monorepo (which are not available). Is it possible to minify things enough that they can be reproduced locally?
