MSVC cl.exe and clang-cl

Purpose

Guide agents through Windows C/C++ compilation: MSVC cl.exe, clang-cl as MSVC-compatible driver, MSBuild project settings, and runtime library choices.

Triggers

• "How do I compile with MSVC from the command line?"
• "What is the MSVC equivalent of -O2?"
• "/MT vs /MD — which do I use?"
• "How do I use clang-cl instead of cl.exe?"
• "I'm getting LNK errors on Windows"
• "How do I generate PDB files?"

Workflow

1. Set up the environment
