import io.github.project_minigraf.minigraf.MiniGrafDb

Cascade release

This repo receives a core-release repository_dispatch from the minigraf monorepo cascade whenever a new version of the minigraf core crate is published. The release workflow pins the new version, commits, tags, builds native libraries for all four platforms, and publishes the fat JAR to Maven Central.
