Three ways to smuggle SQLite into Nix

The article discusses how nixpkgs-multiverse uses large JSON files to index package data, but this approach is inefficient because Nix's JSON parser loads entire files eagerly rather than allowing selective queries. The author explores using SQLite as a better alternative for storing and querying the index data efficiently, and begins examining ways to integrate SQLite into Nix despite the lack of native support, starting with the `builtins.exec` builtin.
