Plugin engines (Opus55, Qwen, Terra) each add two projects at the repo root, and more are coming; at a dozen they would outnumber the core projects. They are also a different kind of thing: out-of-solution, runtime-loaded plugins. Grouping them under Engines/ keeps the root readable. Engines/Directory.Build.props now holds the shared TFM, nullable and implicit-usings settings and the OpenNest.Engine reference, so a new engine's csproj is nearly empty. The tests/ compile exclusion lives in Directory.Build.targets because a removal in .props runs before the SDK adds its default Compile glob and has no effect. Build-Engines.ps1 replaces the per-README manual build-and-copy steps for deploying engines into the benchmark's runtime Engines/ folder. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
