Changes for version 0.19 - 2026-09-03
- Fix LRU accounting, reserve()'s ceiling, sharded iteration, writes to frozen maps and NUL bytes in paths; remove the v9 upgrader.
- Incompatible: upgrade_file() and hashmap-shared-upgrade are gone and v9 files no longer open; a TTL or limit argument of 2**32 or more croaks instead of wrapping; an unreachable $max_size warns.
- Correct the benchmark units and many API and crash-safety notes.
