Phase G: scaffold .NET 10 + SignalR backend (engine port + hub + auth)

- server/ monorepo: Hokm.Engine (C# port of TS engine+AI, validated by sim), Hokm.Server (SignalR GameHub, in-memory matchmaking/rooms, server-side turn timers + bot fill + disconnect handling, per-seat state broadcast), Hokm.Sim - JWT dev auth (OTP 1234 + email); CORS for the Next client; /hub/game - NuGet restored from mirrors (Soroush Nexus + Liara); NuGetAudit off - README + .NET .gitignore; static class Engine renamed Rules (namespace clash) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
