Switch from zstd to pzstd for snapshot archival. pzstd produces multiple independent zstd frames that clients can decompress in parallel. The output is a valid zstd stream readable by any standard zstd decoder.

Add a /snapshot.tar.pzst endpoint that serves snapshots compressed with pzstd (multiple independent zstd frames). Clients can decompress frames in parallel. On cache miss the snapshot is generated on-demand with pzstd and backfilled to the cache. Stacked on #293.
