📝 Info: New OSV ignore lacks required documentation

The file header requires each entry to document a real advisory unfixable without breaking the build, with reachability reasoning. The new GHSA-ggr8-5vv4-36mx entry only states reason = "deepmerge-ts is not a prod issue", far short of the convention the other entries follow.
