Bootstrap.ps1

# ShaderLab — first-time setup script
#
# Runs the per-build helpers that MSBuild would otherwise run on first
# build, plus a NuGet restore and an optional Debug|x64 smoke build, so
# a fresh clone is ready to F5 in one command.
#
# Usage:
#     .\Bootstrap.ps1            # cert + ExprTk + restore (no build)
#     .\Bootstrap.ps1 -Build     # the above + Debug|x64 smoke build
