637972f363reimplemented for the pack-based repository format: the repository is processed pack after pack - each pack is read as a whole and, if it has objects not stored with the desired compression, those get recompressed and the pack is rewritten (objects already fine are copied into the new pack unchanged), the chunk index is updated and the old pack is deleted. a pack whose objects all already match is not touched at all. - new Repository.transform_pack: rewrite one pack, passing each indexed object's bytes through a transform callback. gap bytes are handled like in compact_pack: superseded duplicates are dropped, other unindexed bytes are carried forward for "borg check --repair". - factored the check_pack_objects / superseded_gap_ranges helpers out of compact_pack, now shared with merge_packs and transform_pack. - crash safety like compact (#9748): stored chunk indexes are invalidated before the first store change, a full updated index is written back at the end. SIGINT stops cleanly at a pack boundary, saving a valid index; a later run recompresses the remaining packs. - --stats reports rewritten packs, per-object outcomes (recompressed / already had the desired compression / kept as-is because recompression brings no gain) and the repository size change. - re-adding the fish completions also restores the compression_methods definition that the create/transfer/recreate/import-tar completions kept referencing after it was removed together with the old repo-compress.
