Port to Pi SDK #1
Description
Currently the NixOSandbox utilizes an API to interact and manage everything from the filesystem, bash, skills, dstack, and browser. This creates a less flexible experience for agents to make changes without breaking the sandbox functionality. To make this sandbox more useful whole preserving the reproducibility of Nix, we will Port the solution to be Pi SDK compatible for managing the NixOS sandbox.
Build a plan using nobody-plans-for-pi to brainstorm and write an effective plan to execute the refactor of the nixosandbox codebase.
