/// Single, process-wide ModernUO bootstrap for the UOContent test host. Mirrors Server.Tests'
/// TestServerInitializer in name and shape; kept as a separate (non-shared) copy because this
/// one loads the UOContent assembly and configures the UOContent-specific systems. Both types
/// are <c>internal</c> so the shared name stays scoped to each assembly.
///
/// ModernUO bootstraps its global singletons (Core, ServerConfiguration, AssemblyHandler,
/// NetState/io-ring, World, Timer, the serialization workers, and TileData) exactly once per
/// process. <see cref="World.Load"/> is guarded to run once, and
/// <see cref="World.ExitSerializationThreads"/> must run once against the live workers. Each
/// xUnit collection gets its own fixture instance, so this guard makes the bootstrap run a
/// single time regardless of how many collection fixtures are constructed. The two stateful
/// collections use <c>[CollectionDefinition(DisableParallelization = true)]</c> so they never
/// overlap; pure tests still run in parallel.
