Present pagemap entries currently imply one PAGE_SIZE payload per page. That is not enough to locate packed zero, raw, and LZ4 blocks or to describe region compression. Record the compression mode and region size in the inventory. Add packed per-block sizes, their total, and the region width to pagemap entries, plus PE_PAYLOAD_ALIGNED for entries whose payload starts after padding. Keep the fields optional so ordinary and older images retain their existing representation. Assisted-by: Codex:GPT-5 Signed-off-by: Radostin Stoyanov <rstoyanov@fedoraproject.org>
