Merge pull request 'chore: adopt the NAPALM driver standard' (#8) from chore/driver-standard into main

- CI moves to .gitea/workflows/ci.yml and calls the shared driver workflow
  of NAPALM/driver-standard; .github/ is gone.
- setuptools>=77 with the SPDX license string, no License classifier,
  Python 3.13 classifier, napalm-device-types>=4.21.1, a dev extra with
  floors, Issues and Changelog links; README installs from PyPI and links
  pyVmomi on PyPI.
- mypy strict for the package (the blanket ignore_missing_imports is now
  limited to napalm and yaml); exempt for now (35 errors): _inventory,
  _session, _tasks, base, esxi, parse.environment, parse.snapshots,
  parse.vm_devices, provision.seed, provision.transfer, provisioning.
  Recorded in the quality baseline with the long and complex functions.
- Coverage floor 97 % (measured 97.11 %).

+The first release 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. Python 3.10 remains the floor;
+  requires napalm-device-types 4.21.1.
+- Provisioning fails, and removes the imported VM, when vSphere hands back fewer
+  network adapters than NICs were asked for, instead of leaving a NIC unconfigured.
+  A failed abort of the import lease is logged at debug level.
+
 ### Added
 - VM provisioning (`create_vm_from_cloud_init`, `destroy_vm`,
   `get_vm_status`, `get_network_targets`, `get_image_storages`) from qcow2/raw

 - Declares `open-vm-tools` as the guest agent for provisioned VMs.
 
 ### Changed
+- **Breaking:** `get_device_warnings` is gone; the driver reports facts and the
+  caller names the warnings (netOrk #1111). `get_hypervisor_hosts()` gives each
+  host's connection state (`None` on ESXi, which cannot tell), maintenance mode,
+  configuration issues and managing vCenter (ESXi only); `get_licenses()` gives
+  the assigned licenses with their edition key as `edition`. Requires
+  napalm-device-types 4.14.0; version 0.2.0.
 - The guest agent is declared per guest OS (`GUEST_AGENTS`, napalm-device-types
   3.0); VMware provisions Linux guests only and refuses any other `guest_os`.
 - The NoCloud network-config comes from napalm-device-types
