Adds new SVSim.Hosting project carrying Serilog + Serilog.AspNetCore + Serilog.Settings.Configuration + enricher package refs, and a single IHostBuilder extension method UseSvSimSerilog(appName) that installs a colored console sink and a plain-text file sink rolling daily with a 100 MB per-file cap and 7-file retention. ReadFrom.Configuration is called last so appsettings can override minimum levels per category. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
