- Add WireMockServerSettings.ScribanRegistrationCallback
(Action<object, IFileSystemHandler>?) so code-configured servers can add
functions, objects or variables to Scriban and Scriban-DotLiquid templates.
- Pass the settings to ScribanContextFactory, which invokes the callback with
a new ScriptObject per transformer context.
- Push the custom globals beneath the template model in ScribanContext so
request, response, mapping and data take precedence; keep the original
Template.Render call when no callback is configured.
- Add the strongly typed WithScribanRegistration extension method.
- Add a Scriban example to the .NET 8 console app.
- Make the proxy tests use a local target server instead of www.google.com,
and skip the IPv6 loopback test when the OS has no IPv6 support.
