Build now targets Java 21 for 1.21.x dependency compatibility.
CI/CD: GitHub Actions builds on pushes/PRs, publishes releases on v* tags, and maintains a rolling main-latest prerelease with auto-generated release notes.
Packaging: resource filtering adjusted so .schem files are included correctly.
Visitor protection: fixed ProtocolLib packet handling for block/container interaction restrictions.
Docs/config: added/expanded permission documentation and configuration migration support.
[1.21.10 up2]
Enforce container/workstation access via per-island permissions and visitor settings (blocks external plugins like sell wands on others' chests).
Permission-aware inventory open/interaction handling integrated with IslandPermissionManager.
