delete_in_place ~cfg ~digest ~pack uids modifies the PACK file pack in place. Entries whose UID is in uids, together with the old versions of their transitive delta-descendants, become ghost entries: their bytes remain in the file (so the PACK stays structurally parseable) but they are no longer referenced by the IDX. Fresh copies of every descendant are appended at the end of the PACK (direct children as bases, deeper descendants as carbon-copied deltas with recomputed ofs-delta headers). The header object count and trailer hash are updated accordingly. This operation does not reclaim disk space for the removed/replaced entries.
