When `individualNixPackaging` is enabled, the generated Nix expression now adds `collectCacheScript` and `cacheDrvs` to the project derivation's passthru. Both values reuse the existing `mkCacheBuilderForDrvs` helper. Motivation: consumers sometimes want to materialize `node_modules` (or otherwise run `yarn install`) inside their own derivations while still relying on the cache derivations emitted by Nixify. Today they have to depend on the entire libexec workspace output, which can easily climb into the gigabytes for large repositories. Improve this by exposing the script that copies all per-package cache derivations, as well as the underlying `cacheDrvs` attribute set, so downstream derivations can source the script and populate `.yarn/cache` without copying the full workspace tree.
