Additional notes for reviewers

This plugin requires Windows and Microsoft Excel 2016 or later because it automates the native Excel application through COM. The plugin package contains bootstrap scripts and skills, not executable runtime binaries. On first use it downloads the matching Windows runtime from the public sbroenne/mcp-server-excel GitHub Release. Release v2.0.1 publishes SHA256SUMS, and the bootstrap fails closed unless fresh and cached runtime ZIPs match their exact SHA-256 entry before extraction.
