fix(cmake): quote NuGet install output

[Osraka]

Summary

• quote NUGET_INSTALL_OUTPUT before splitting it into CMake list lines
• prevents string(REPLACE) from receiving too few arguments when the NuGet output is empty or expands unexpectedly
• keeps the existing filtering behavior for Successfully installed / already installed messages

Fixes #237.

Testing

• git diff --check
• Not run: full CMake build requires the Windows SDK / Windows toolchain environment described in README.md and AGENTS.md
