dep-radius: the dependency upgrade detective

Field notes

The documented workflow compares dependency release notes and version types with the project's actual package usage, then emits file-and-line locations for an agent to inspect. Its example follows a zod 4.4.3-to-4.5.0 upgrade through a changed emoji-length rule, a test edit, and four passing tests. The page reports 51 behavior-changing release notes in its test set, with 25 matched to an exact line; unresolved cases remain review results rather than being declared safe.
