Build with ci-workflows gradle.yaml (JDK 17, ./gradlew build); v* tags attach the plugin zip and SHA256SUMS to the Gitea release. The committed gradle-wrapper.jar was not the official Gradle 8.6 jar the properties point at; replace it with the jar from the verified gradle-8.6-bin distribution and pin distributionSha256Sum so Gradle verifies the download.
