Subject: [PATCH] fix: add shell flag for Windows spawn in VSCode extension
 (#2781)

On Windows, npm global installs create .cmd wrapper scripts. Node's
child_process.spawn cannot execute .cmd files directly without
shell: true, resulting in ENOENT/EINVAL errors when the VSCode
extension tries to start the GSD agent.

Closes #2721
