Cobblemon Info for REI / JEI / EMI

Added

• Server-to-client spawn data synchronization — dedicated servers send authoritative spawn/evolution data to connecting clients via compressed chunked packets
• DynamicDisplayGenerator for both spawn and evolution categories — displays now reflect live data without needing a REI reload
• Config system (cobblemon-spawning-rei.json) with debugMode, showSpawnWeights, showEvolutions, localDatapackScan options
• "Server" indicator label on spawn/evolution displays when viewing server-synced data
• Disconnect cleanup: data clears on server disconnect so local data reloads for the next session
• PlatformHelper abstraction for cross-platform config/networking

Changed

• Mod environment changed from client-only to both sides ("environment": "*") to support server-side data loading
• SpawnDataLoader now uses reflection for client game directory access (safe no-op on dedicated server)
• SpawnDataIndex gains DataSource tracking (NONE/LOCAL/SERVER) and awaitingServerData flag
• tickReloadCheck suppressed while awaiting server data
