Allow "post-actions script" with full internet access AFTER the agents have made their changes

What feature would you like to see?

At the moment we can specify script commands int he "setup script" section BEFORE the agents do their thing with full internet access.

I want to also be able to run commands with full internet access AFTER the agents have done their thing.

For example, after updating my nextjs project, I want to run commands programmatically to deploy the code as-is to vercel BEFORE asking for further changes or making a pull request!

Additional information

• Temporary workaround: at the moment, I am building and deploying to vercel in the maintenance script area. So I am having to run the container to ask for changes, which deploys the app before changes to vercel, then changes are made and reported to me. Then I am having to ask to run a dummy task (asking the agent to "Echo the url of the most recent vercel deployment"), which reruns the maintenance script.
