chore: adopt the NAPALM driver standard

- CI moves to .gitea/workflows/ci.yml and calls the shared driver workflow
  of NAPALM/driver-standard; .github/ is gone.
- requires-python >=3.10 (napalm-device-types needs it), LICENSE file,
  py.typed, setuptools>=77 with the SPDX license string, Issues and
  Changelog links on git.netork.io, napalm-device-types>=4.21.1 from PyPI,
  floors on the dev extra.
- mypy strict for the whole package, no module exempt: optional_args is
  dict[str, Any] | None.
- tests/quality_baseline.json records get_facts and get_route_to, over
  complexity 10. Coverage floor 95 % (measured 95.67 %).
- CHANGELOG.md in Keep a Changelog form; the README says no host output is
  recorded yet, links napalm-device-types in the NAPALM org and pypsrp on
  PyPI.

+### Changed
+- The driver follows the NAPALM driver standard
+  (https://git.netork.io/NAPALM/driver-standard): CI on Gitea runs ruff, mypy, the
+  tests on Python 3.10–3.13 and at the lowest declared versions, bandit, pip-audit and
+  a build check, and a release tag publishes to PyPI. The package now ships `py.typed`
+  and a LICENSE file. **Python 3.9 is no longer supported**; napalm-device-types never
+  ran on it, and 4.21.1 from PyPI is now the oldest it accepts.
