cat 76c1fb84c8 internal/pkg: stream decompress artifact 
The tarArtifact predates FileArtifact pipelining. This migrates decompression and buffering into a standalone artifact implementation.

cat 729be19af3 internal/pkg: rename archive checksum helpers 
These names are more consistent with other helper names, so rename them while the API is still internal.

cat 42cea1e7c6 internal/pkg: streaming archive reader/writer 
This is much more robust and efficient than the simple buffering implementation for larger files. Allocations happen almost exclusively in WalkDir.
