[1.15.0] - 2025-06-16

Full Changelog: v1.14.6...v1.15.0

note: starting with v1.15.0, kubenurse switches from prometheus client_go library to the more lightweight VictoriaMetrics metrics library.
Standard prometheus histograms are still supported, and VictoriaMetrics histograms can be selected as a replacement with the KUBENURSE_VICTORIAMETRICS_HISTOGRAM="true" env variable (those are much more precise but are only compatible with VictoriaMetrics though).
