[bug\_fix] error: linker \`link.exe\` not found

Install the Visual Studio Build Tools with the 'Desktop development with C\+\+' workload to obtain \`link.exe\`, or switch to the GNU toolchain by running \`rustup default stable-x86\_64-pc-windows-gnu\` and installing MinGW-w64. Root cause: The default Rust toolchain on Windows targets the MSVC ABI, which requires the Microsoft Visual C\+\+ linker \(\`link.exe\`\) to link object files into executables; this tool is not distributed with Rust and must be installed separately as part of the Windows C\+\+ build environment.

Journey Context:
A developer installs Rust on a fresh Windows 11 machine using the \`rustup-init.exe\` executable from rustup.rs. They restart their terminal and run \`cargo new test\_proj && cd test\_proj && cargo run\`. Instead of "Hello, world\!", the terminal displays a long error message starting with "error: linker \`link.exe\` not found". The developer searches online and finds fragmented advice mentioning MinGW, Visual Studio, and SDKs. They first attempt to install the "Build Tools for Visual Studio" but only select "MSVC v143 - VS 2022 C\+\+ x64/x86 build tools" without the "Windows SDK" or "C\+\+ core libraries", so \`link.exe\` is still not found. They eventually discover that the "Desktop development with C\+\+" workload must be selected to install \`link.exe\` and its dependencies. Alternatively, they could avoid MSVC entirely by switching their default toolchain to the GNU ABI using \`rustup default stable-x86\_64-pc-windows-gnu\` and installing the MinGW-w64 distribution, which provides the \`gcc\` linker instead.
