- Updated io.Medium interface with Open() and Create() methods to support streaming. - Migrated pkg/build, pkg/build/builders, and pkg/build/signing to use io.Medium. - Added FS field to build.Config and updated build.Builder interface. - Refactored checksum and archive logic to use io.Medium streaming. - Updated pkg/release and pkg/build/buildcmd to use io.Local. - Updated unit tests to match new signatures.
