So far, we provided a custom `default.nix` in the root of the tvix josh workspace, which re-defined the shell attribute from `tvix/default.nix`. Some of the recent fixes, e.g. the MacOS-specific additions to the list of dependencies however didn't get ported over to this file, and in general, it's quite annoying to have two different places for these things. Initially I explored the idea of moving this default.nix file to a default-depot.nix file in the josh worktree only, and then "polyfill" some of the dependencies, or set up readTree in the josh workspace too, but it turned out to pull in too many dependencies to be worth the effort (nix.sparseTree, tools.depotfmt, crate2nix overlay, third_party.gitignoreSource). I now took a different approach - moving the definition of the `shell` attribute from `tvix/default.nix` to its own `shell.nix` file, which is imported from `tvix/default.nix` in regular depot usecases. Josh workspace consumers only see the `shell.nix`, which can be used in a self-contained fashion, the other `default.nix` is gone entirely, and we update the workspace file to also not show `tvix/default.nix` at the root either, so running `nix-shell` and then `cargo build` should still work.
