Release 0.5.0-rc.1

0.4.1's release candidates grew into 0.5.0: exposure checks, certificates, linked zones, encrypted DNS and per-view statistics are new features. The upgrade from 0.4.0 packages was tested in a Debian 13 container. The CLI's filtered stats summary says answers for the busiest minute too.
