Every CI run died at "pip install -e .[dev]": pyproject.toml asks for
napalm_device_types, which lives in git.netork.io/NAPALM rather than on PyPI,
and pip found only an unrelated 0.1.0 there. Not one test had run in CI.
The workflow now installs napalm-device-types from git first. The matrix
drops 3.8/3.9 and requires-python says >=3.10, because napalm-device-types
itself needs 3.10 -- the package never installed on anything older.
Replayed in a fresh venv: napalm-device-types 2.0.0 from git, then the
package with its dev extras, tests green.
