Add Nexo custom block support

[Copilot]

• Explore codebase and understand custom block architecture
• Add Nexo API dependency to pom.xml (repository + dependency + version property)
• Create NexoCustomBlock.java in oneblocks/customblock/ (similar to ItemsAdderCustomBlock)
• Create NexoListener.java in listeners/ (similar to ItemsAdderListener, listens for NexoItemsLoadedEvent)
• Update AOneBlock.java to register Nexo support when Nexo plugin is present
• Fix build: exclude all transitive deps from Nexo dependency (libby-bukkit, triumph-gui unavailable)
• Run code review and address feedback
• Run CodeQL security check (no alerts)
• Run dependency vulnerability check (no vulnerabilities)

Comments on the Issue (you are @copilot in this section)

@tastybento Nexo docs: https://docs.nexomc.com/ https://docs.nexomc.com/community-guides/api https://jd.nexomc.com/1.15/

The aim is to be able to specify Nexo blocks in the phases so that they can be generated by the magic block just like vanilla blocks. See https://jd.nexomc.com/1.8/com/nexomc/nexo/api/NexoBlocks.html
This would require the Nexo Plugin and the code must check if the Nexo plugin is there or not - it is NOT required, just optional.</comment_new>

@copilot There are dependency issues with the building. Fix them.

Fixed in 932ee9f. The Nexo dependency had transitive dependencies (net.byteflux:libby-bukkit:1.3.1 and dev.triumphteam:triumph-gui:3.2.0-SNAPSHOT) that weren't available in any of the configured Maven repositories. Since Nexo is provided scope and we only need its API classes at compile time, I excluded all transitive dependencies with a wildcard exclusion.
