Fixed Maven publishing

- ItemsAdder API resolves from Maven Central
- Integration repositories only resolve their assigned groups and modules
- Shared VolmLib classes and packaging use the same pinned revision
- JitPack builds and publishes with remote dependencies
- Local Maven publication uses art.arcane:iris with the configured version
- API generation tracks the final archive filename lazily
- API jars retain signatures and metadata with valid throwing method stubs
- Publication tests verify metadata, bytecode, and consumer compilation
