<!--
Shorten the project's output folder segment to stay under Windows
MAX_PATH (260) on CI. VSSDK's GenerateTemplatesManifest extracts every
vstemplate .zip under $(IntermediateOutputPath)$(TargetFramework)\...,
which combined with the ~32-char Dev17 project names and deep template
asset paths overflows on CI (repo root C:\__w\1\s\WindowsAppSDK\) and
aborts with VSSDK1300. Cpp17/Cs17 save ~27 chars per path; other
projects keep $(MSBuildProjectName) for diagnosability.
