Changes for version 0.13 - 2026-09-22
- FIXES two carves refused in four thousand on a loaded FreeBSD 15 smoker, with room in the arena for all of them.
- A carve refused for a held stripe answers SA_E_BUSY, not SA_E_FULL: one means try again, the other means stop.
- Add Shared::Arena::_last_err: why the last ->region returned empty.
- FIXES t/32-map-ttl.t counting three hits where it asked for two.
