fix: add --compressed to chunkah args and clean buildah cache before rechunk

Browse Source 
chunkah OCI archive (6.7 GiB uncompressed) did not fit on runner alongside
original image. --compressed uses zstd compression, reducing archive to ~3-4GB.
Also cleans buildah cache before rechunk to free additional space.
