refactor: Update make script to handle loca/editable + CI/non-editable

[pawamoy]

uv_install() {
    uv pip compile pyproject.toml devdeps.txt | uv pip install -r -
    if [ -z "${CI}" ]; then
        uv pip install -e .
    else
        uv pip install "devboard @ ."
    fi
}

In CI workflow, then just use make setup in test jobs.
