v0.39.0 Release Summary
This release focuses on strengthening block verification and the write-record-block (WRB) pipeline: it adds real TSS signing for verification tests, sidecar integrity validation with orphan-sidecar cleanup, and live-push of new WRBs to a Block Node. Server Status API gains a next-expected-block field and fixes for earliest-managed-block handling, while backfill and persistence-notification edge cases were hardened. The Health Plugin now runs on its own Helidon Webserver, and charts gained load-balancer support for multiple ports. The rest is routine dependency bumps and CI/release-automation cleanup.
