Push command-line should have an option to wait until the package is publicly available

NuGet Product(s) Affected

dotnet.exe, NuGet.exe

Current Behavior

dotnet nuget push returns as soon as a package is pushed to the server.

Desired Behavior

In automated workflows, packages are pushed. In some cases, it would be nice if the push command also had a --wait argument so that the process checked with the feed until its passed all validation.

This could be especially helpful for MCP server pushes where a pipeline will push a package and then publish to an MCP registry. Publishing will fail if the NuGet package is unavailable so each individual person would need to implement some sort of mechanism to wait for the package to be available or just have two different pipelines.

Additional Context

This would need some design. Some complexities to consider:

• A single push command can push multiple package ID/versions. You'd probably want to poll on them all in a smart way.
• Push can upload .snupkg files, which currently have no way in the NuGet protocol to check for availability. Technically you could check with the symserv protocol but that would be a new sort of client implementation in NuGet.

This would be a very useful capability for the .NET team to have for the overall product release process. We currently upload a number of NuGet packages in in logical batches, where each batch must be able to be restored by clients before the next batch goes in. An example scenario is workload sets - we'd ideally like to

• upload all of the individual workload packs and
• have them restore-able
• push the workload manifests (which point to the individual packs)
• have them restore-able
• push the workload sets (which point to versions of workload manifests)

being able to enforce this ensures that
a) no one can use the new packs before the whole system is populated, and
b) no one is subject to 'tearing' where the manifest may be available but some packs are not yet restore-able.
