The Python environment bundled with the Checkmk Windows agent no longer includes the pyOpenSSL package.

pyOpenSSL was an unused dependency and is not imported by the agent or any of its plugins. Removing it reduces the size as well as the dependency and CVE surface of the bundled Python environment.

There is no functional change for users.
