Sandbox-runtime fixes the Windows install command in its error output

A one-constant fix in anthropics/sandbox-runtime aligns the Windows error message and the README on the scoped install command, so operators following a failed setup get a path that actually resolves.

windows: correct the npx command for windows-install anthropics/sandbox-runtime

by ant-kurt

Windows error messages used to tell operators to run an unscoped `npx sandbox-runtime windows-install`; they now print `npx @anthropic-ai/sandbox-runtime windows-install`, matching the README. The string lives in one constant with a test pinning `src/` and the README to the same spelling, so your copy-paste from an error panel no longer diverges from the docs.

The merge that lands the corrected command on the mainline; setup on Windows is unchanged once the scoped command runs.
