.NET: Samples and Demos showing Deployment of Workflows inside and outside of Foundry

We need to create samples and demos that show different ways of deploying and hosting workflows. Some ideas include:

- Declarative workflow hosted in Foundry
- Declarative workflow hosted in-process and deployed using docker image
- Pro-code workflow deployed in Foundry Container Agent
- Pro-code workflow hosted in-process and deployed using a docker image

Start by mapping the four deployment scenarios listed in the issue: declarative and pro-code workflows, each hosted in Foundry or in-process with a Docker image. Review the existing .NET workflow and deployment examples before deciding the sample structure. Done means samples and demos cover all four scenarios and clearly show how each workflow is hosted and deployed.
