new feature: publish the source and lock files for binaries (oli, oay...)

### Feature Description

Could you publish the source code and lockfile for the binaries as part of the release ?

### Problem and Solution

Not having the source code for binaries makes it hard to publish this to nixos which adopts a build from source philosophy.

Having the code for the binaries would make it possible to package to nixpkgs.

### Additional Context

I feel I've already opened a similar issue but couldn't find it.

### Are you willing to contribute to the development of this feature?

- [x] Yes, I am willing to contribute to the development of this feature.

Review the release process for the oli and oay binaries and identify where their published artifacts are assembled. Determine how the corresponding source code and lockfile should be included so NixOS/nixpkgs can build them from source, then verify a release contains both artifacts for each binary.
