Subject: [PATCH] Switch dev tooling to containers

Move away from local installed Crystal and use `hydrofoil-crystal`
container image as runtime environment.

The included `docker-compose.yml` and `Procfile.dev` files setups everything
that is needed to automatically run the project's specs.

To start watching for changes, in a console:

    $ docker compose up

(Use `docker-compose` if you're still using old version of Docker Compose)

You can press `Ctrl+C` to stop it or from another console:

    $ docker compose stop

[skip ci]
