Scaffold a new in-house Folia/Paper plugin for the FoliaNexa cluster (folia-server repo), either from a feature description or by pointing at an existing mod/plugin on Modrinth and producing an original, Folia-native plugin that replicates its player-facing behavior. Use when a developer asks to create/write/build/port a plugin for this cluster, or says something like "make a plugin like <modrinth URL>" / "port this mod to Folia". Covers requirement gathering, the Modrinth lookup + feature-triage procedure (and its legal/ethical boundaries — never copy source, always disclose inspiration), the Gradle/Java 21/paper-api project skeleton, Folia-safe RegionScheduler/GlobalRegionScheduler/AsyncScheduler usage, and wiring the finished plugin toward mgmt/src/folia_mgmt/catalog.yaml per docs/plugin-dev/03-submitting-for-review.md.
