Pull Request Overview

This PR enables worker indexing for Logic Apps when running in codeful mode behind an environment variable setting. The change allows Logic Apps to use the dotnet worker runtime with specific environment variables while maintaining backward compatibility with existing Logic Apps that don't use codeful mode.

• Adds WORKFLOW_CODEFUL_ENABLED environment variable support to control codeful mode behavior
• Modifies worker indexing logic to allow indexing for Logic Apps when codeful mode is enabled
• Disables strict worker runtime validation for Logic Apps in codeful mode

I have a few questions/comments related to this PR -

• Do we need these changes in dev branch? My understanding is that Logic apps uses in-proc branch only. We may need for consistency purpose between dev and in-proc - but double checking this.
• Could you please complete the PR checklist in the description and add to the release notes?
• It would be helpful if you can create a github issue and provide context about the changes. I am not very clear about the ask and changes here. Please link github issue in the PR description.
• Please add some tests too.

Let me know if you need help with any of these items, happy to assist.
