Setting up the different tools for development can be hard for new
contributors. This commit adds a Nix flake that provides a reproducible
development environment which is easy to set up and ensures consistent
code style across all subprojects.
The initial flake contains `git`, `pre-commit`, `which` and `bazelisk`
wrapped as a `bazel` executable. Dependencies like Rust, Scala etc may
be added in the `packages` attribute in the future.
The current pre-commit configuration is a no-op. Future commits may
enable the currently disabled parts of `pre-commit-hooks.nix` for a
gradual transition.
Supports `(x86_64|aarch64) (Linux|MacOS)` systems.
Please note we have force-pushed a new initial commit in order to remove some publicly-available Twitter user information. Note that this process may be required in the future.
