Add .envrc and improve tooling

The `.envrc` is for `direnv`, which will automatically create and activate the venv when opening the workspace directory.

Other than that, this also adds a `.python-version` and updates various Python versions to 3.12.

Also the redundant CI `build` job is being removed.
