WorldEditDisplay 2.2.0 Selection Sharing, Multi-Platform Support & Performance Improvements
Summary
Major release introducing a Selection Sharing System that lets players share their WorldEdit selections with others in real-time, expanded multi-platform support (Paper, Folia, Spigot), a new RegionRenderer abstract base class for a more extensible rendering architecture, and numerous performance improvements with render caching and async operations.

New Features
Selection Sharing System

• Added /wedisplay share command to invite other players to view your selection
• Selections shared in real-time with persistent storage across sessions
• Each shared selection is assigned a unique color generated automatically
• Unused shared colors are released when sharing ends to optimize resources
• Permission-based access control: worldeditdisplay.share required to use share commands
• Share manager configuration is reloadable via /wedisplayreload

RegionRenderer Abstract Base Class

• Introduced RegionRenderer abstract base class for a unified and extensible rendering architecture
• Simplifies adding new region types and customizing render behavior

Multi-Platform Support

• Added official support for Folia (region-threaded scheduling)
• Added official support for Spigot (in addition to Paper)
• Task scheduling is now platform-aware and routes to the correct scheduler automatically

Region Bounding Box & Distance Utilities

• Added bounding box calculation methods to region objects
• Added distance calculation methods between regions and players for range-based optimizations

Improvements
Rendering Performance

• Introduced renderer-level caching to reduce redundant computation
• Name cache logic for shared renders is now correctly invalidated to avoid stale reads
• Clearing a sharer's render now properly releases associated resources
• Render brightness and label position adjustments for improved visual quality

Async Settings I/O

• Player settings are now saved asynchronously to prevent main-thread blocking
• Config saves are deferred to a scheduled task to avoid repeated disk writes during rapid state changes

Thread Safety

• Share request timeout is now stored in a thread-safe mutable field
• Player multi-region map is now returned as an unmodifiable view to protect data integrity

Bug Fixes

• fix(render): Corrected shared render name-cache invalidation logic to prevent unnecessary re-reads
• fix(player): Returned unmodifiable multi-region map to protect internal data from external mutation
• fix(share): Made share request timeout mutable for proper thread-safe handling
• fix(render): Adjusted brightness calculation and label position for better display results

Technical & CI Updates

• Updated GitHub Actions workflow file versions for improved stability
• Added adventure-api exclusion filter to the Spigot Maven profile to prevent class conflicts
• Removed SHARE-DESIGN.md design document (merged into implementation)
