We use the standard toolcache API to decompress bundles, but when decompression fails, we only get the exit code from the toolcache API, which isn't very helpful for debugging.
Therefore this PR calls
tar
directly when decompressing Zstandard bundles to provide better quality failure information. A large part of the PR is a refactor to expose the functionality we use for invoking and capturing errors from the CLI in a generic way.Merge / deployment checklist
