Remove the legacy CsWinMD authoring tool and its tests, and update build/CI and docs to use the new WinMD authoring targets. Deleted CsWinMD project, binaries, NuGet spec/targets and test CSWinMDComponent files; renamed Microsoft.Windows.CsWinMD.Generator.targets to Microsoft.Windows.CsWinRT.Authoring.WinMD.targets and updated Microsoft.Windows.CsWinRT.targets import. Cleaned up Azure pipeline templates and build scripts to stop staging/packing CsWinMD, removed the PublishCsWinMD variable, and updated documentation and solution entries to reflect the change.

* Add Benchmarks and Hosting folders to solution Reorganize cswinrt.slnx by introducing /Benchmarks/ and /Hosting/ folders. Move Benchmarks.csproj into /Benchmarks/ and add its BuildDependency entries and platform mappings. Relocate TestWinRT/BenchmarkComponent and Tests/ObjectLifetimeTests entries (with platform/build flags) to match the new folder layout. Move Authoring/WinRT.Host.Shim and WinRT.Host projects into /Hosting/ and adjust WinRT.SourceGenerator2 placement. Preserve existing platform and Build attributes while updating the solution ordering. * Fix NuGet folder casing in solution Update src/cswinrt.slnx to change the Folder Name from "/Nuget/" to "/NuGet/" for consistent casing. This avoids potential issues on case-sensitive filesystems and keeps the solution aligned with standard NuGet naming.

The CsWinMD tool and its CSWinMDComponent test were removed in #2408, but the projection generator port (#2440) accidentally re-added the orphaned CSWinMDComponent.vcxproj.filters file. It is the only remaining file in the directory, is not part of any solution, and is referenced by nothing. Remove it (and the now-empty directory).

Summary
Remove the legacy
cswinmdauthoring tool and its associated test component, plus all related leftover infrastructure (NuGet spec, MSBuild targets, CI steps, build scripts, solution entries). The WinMD generation responsibilities are now fully owned by the newcswinrtwinmdgentool (src/WinRT.WinMD.Generator/). The remaining authoring WinMD targets file is renamed for naming consistency with the rest of the CsWinRT 3.0 targets.Motivation
With CsWinRT 3.0, WinMD generation has moved entirely into the new
cswinrtwinmdgen.exepost-build tool, which is consistent with the other 3.0 build tools (cswinrtimplgen,cswinrtprojectiongen,cswinrtinteropgen). The oldcswinmdproject, its standalone NuGet package, and the C++CSWinMDComponenttest project are no longer used and only added clutter to the repo, the solution, and the CI pipeline. RenamingMicrosoft.Windows.CsWinMD.Generator.targetstoMicrosoft.Windows.CsWinRT.Authoring.WinMD.targetsaligns its name with the existingMicrosoft.Windows.CsWinRT.Authoring.*.targetsfamily.Changes
src/Authoring/cswinmd/: deleted the legacy CsWinMD tool project (CsWinMD.csproj,Program.cs).src/Tests/CSWinMDComponent/: deleted the C++ test component that depended on the old tool (vcxproj, headers, sources,.def, props,packages.config).nuget/Microsoft.Windows.CsWinMD.nuspecandnuget/Microsoft.Windows.CsWinMD.targets: removed; the standalone CsWinMD NuGet package is no longer produced.nuget/Microsoft.Windows.CsWinMD.Generator.targets→nuget/Microsoft.Windows.CsWinRT.Authoring.WinMD.targets: renamed for naming consistency with other authoring targets.nuget/Microsoft.Windows.CsWinRT.targets: updated the import to reference the renamed targets file.src/build.cmd: removed thecswinmd_outpathvariable and the secondnuget packinvocation that built the CsWinMD package.src/cswinrt.slnx: removed theCsWinMDandCSWinMDComponentsolution entries; tidied up theFiles/src/folder paths to be solution-relative.build/AzurePipelineTemplates/: removed CsWinMD build/stage/publish steps fromCsWinRT-Build-Steps.yml,CsWinRT-BuildAndTest-Stage-OneBranch.yml,CsWinRT-PublishToNuGet-Steps.yml, and thePublishCsWinMDvariable fromCsWinRT-Variables.yml.docs/structure.mdand.github/copilot-instructions.md: updated references to the oldcswinmdtool and the renamed targets file..github/skills/update-copilot-instructions/SKILL.md: minor doc update to match.
