Server-side mod for SPT (Single Player Tarkov) that powers the SPT Leaderboard v2 system. Handles profile data collection, inbox notifications, ragfair utilities, and API routes for the leaderboard backend.

Forked from SPT-Leaderboard/Server and modernized:

• Updated to SPT 4.0.5 — NuGet packages SPTarkov.Server.Core, SPTarkov.Common, SPTarkov.DI all at 4.0.5
• SDK-style .csproj — modern project format, .NET 9.0, C# 12
• Namespace renamed — SPTLeaderboard → SPTLeaderboardV2Server
• New GUID — com.sptleaderboard.v2.server
• Bug fixes:
  • SessionInboxChecks: Dictionary → ConcurrentDictionary for thread-safe concurrent route access
  • InboxCallbacks: Added try-catch inside fire-and-forget Task.Run() to prevent silent failures
  • RagfairUtils: Requirements?.First() → FirstOrDefault() to prevent exceptions on empty collections
  • ItemCallbacks: Removed unused using Microsoft.AspNetCore.Components
• Consistent logging — all files use ISptLogger<T> (was mixed with ILogger<T>)
• File-scoped namespaces — modern C# style throughout

1. Build: dotnet build -c Release
2. Copy output to SPT/user/mods/SPTLeaderboardV2Server/

• SPT 4.0.5+
• .NET 9.0 SDK (build only)
