Advantages:
- Pure test evaluations
- The test framework can now be used by flakes that extend nix-bitcoin
- Most features of `run-tests.sh` are now accessible via `nix build`/`nix run`.
We keep `run-tests.sh` for advanced features like `scenarioOverridesFile` and adhoc scenarios.
Other changes:
- `run-tests.sh` now builds aggregate VM tests like `basic` or
`buildable` by creating all VMs in a single evaluation.
This speeds up the tests and eases debugging by separating the eval and build steps.
- Use the new `nix` CLI which has improved build output logging
by prefixing output lines with the origin drv name.
Instead of setting up the script PATH via nix-shell, use
`nix shell` with inputs from the nix-bitcoin flake.
Advantages:
- Uses the nixpkgs version from the nix-bitcoin flake instead of
`<nixpkgs>` from the user env (NIX_PATH), so the script runtime
env is reproducible.
- The pkg derivations for the runtime env are cached, which greatly
increases script startup speed.

The latest nixpkgs-unstable update would require node-based packages to
distinguish between stable and unstable when building. Instead of dealing with
that complexity, we will only guarantee compatability of our packages with
stable.
- Don't fail on `kill $cachixPid` when cachix has already exited.
This fixes some failing CI builds.
- Stop the cachix background worker before the final `cachix push`.
This can avoid unneeded reuploads.
Use the coreutils version of tail on cirrus which supports
argument --pid.
- Make more economic use of the free CI resources by removing redundant build tasks:
- Build unstable pkgs in a single separate task ("pkgs_unstable").
- All stable pkgs are implicitly built by the modules tests.
- The build script (ci/build.sh) can now be executed locally for easier
debugging.
- Use an explicit 'cachix push' command instead of helper/wait-for-network-idle.rb.
This is simpler and more reliable.
