Isolate UseDotNet download and extraction files in a dedicated Linux temp directory, then remove it before tests and packaging. Record disk usage around installation, cleanup, and the build to quantify savings and identify remaining pressure. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Use the observed agent temp location and compare entries before and after SDK installation. Remove only newly created GUID-named SDK archives and extraction directories, leaving other temp entries and installed SDKs intact.

Closing as no longer needed after #3862 moved Linux CI to the engineering-managed agent. The rebased build finished with 83 GB free on the workspace volume; the additional SDK-staging cleanup is not worth maintaining. |

Why
Linux jobs in Azure Pipelines builds 1607887 and 1607792 ran out of disk while packing NuGet packages. UseDotNet@2 v279 downloads and extracts .NET 8/9/10 SDKs into the agent temp directory before copying them into
.dotnet.Change
CI follow-up
The first PR build, 1608096, passed both Linux configurations but revealed that the original per-task temp override had no effect: 2.4 GB remained in the agent temp root while the dedicated staging directory was empty, and Linux ended at 100% disk usage. After rebasing onto #3862, build 1609320 passed both Linux configurations on the .NET engineering-managed Ubuntu agent. Its workspace volume is 98 GB. Each job measured 2.4 GB of SDK staging after installation and about 20 KB after cleanup; at the end of build and packaging, 83 GB remained free on that volume (12% used). Windows Debug and Release also passed; the earlier Windows Release xUnit failure was unrelated to this Linux-only change. The Microsoft.Extensions compatibility issue is separately tracked in #3833.
