chore: adopt the NAPALM driver standard

- CI moves to .gitea/workflows/ci.yml and calls the shared driver workflow
  of NAPALM/driver-standard; napalm-device-types and napalm-linux come from
  git until napalm-linux 0.15.0 is on PyPI.
- requires-python >=3.10 (napalm-device-types needs it), SPDX license
  string, setuptools>=77, LICENSE file, py.typed, links to git.netork.io.
- Dependencies: napalm-device-types>=4.22.0, napalm-linux>=0.15.0,
  napalm>=4.0 (tested at 4.0.0); dev extra with pytest, pytest-cov, mypy
  and ruff.
- mypy strict for the whole package, no exempt module: _omv_read is
  annotated as returning list[dict[str, Any]] (types only).
- Coverage floor 15 % (measured 15.89 %); the four long getters and the
  complexity of get_disks are recorded in the quality baseline.
- README (what it is, how it connects, the getters, what it does not do)
  and CHANGELOG are new.
- The committed egg-info and __pycache__ files are untracked; .gitignore
  from the template keeps them, .venv and build output out.

+## [Unreleased]
+
+### 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`,
+  a README and a LICENSE file. It needs napalm-device-types 4.22.0 and napalm-linux
+  0.15.0. **Python 3.9 is no longer supported**; napalm-device-types never ran on it.
+- Failures the driver deliberately ignores (the OpenMediaVault version, `smartctl` for one
+  disk, `/proc/mdstat`, `mdadm --detail`, a shared folder lookup) are now logged at debug
+  level.
