Mira PR Walkthrough

This PR isolates integration-sync dry runs from the caller’s working repository by cloning the repository into a disposable temporary directory, copying local branch refs, and running the sync inside that clone before cleanup. It adds coverage for both ordinary repositories and colocated Jujutsu working copies, ensuring HEADs, refs, remotes, working-tree state, and files remain untouched. The change also introduces a reproducible Nix development shell and updates CI and publishing workflows to run dependency installation, artifact/eval checks, and tests through that shell.

Confidence: 4/5   ◉◉◉◉○   Safe with minor fixes

• The isolation path is narrowly implemented and backed by focused integration tests, including a colocated Jujutsu case; the main residual risk is operational behavior of cloning/copying refs across unusual repository or remote configurations.
