New features:
- create/import-tar --quick-stats: faster than --stats by omitting "All archives"
and repository chunks statistics, #9579
and repository chunk statistics, #9579
- prune: show total vs matching archives in output, #9262
- Minimal implementation of "related repositories", #9645
This feature allows multiple repositories to share deduplication-relevant secrets (id_key and chunk_seed) while maintaining secure, independent encryption keys.

- Make it possible to look up in compacted hashtables.
- Avoid buckets_length integer overflow on 32-bit systems via huge num_buckets.
- Deal safely with empty index: we must use num_buckets = 1 to avoid division
by zero and sanity check in hashindex_read.

- Reinitialize upper/lower limit and min_empty after compact.

- Correctly free memory when header validation fails.
- BaseIndex.clear: always stay in valid state.
Do not free the old index before we successfully have allocated a new one.
