-Align devDependency versions with the exact resolutions in the workspace lockfile for `packages/eslint-config` (ESLint core and all related plugins/configs). Peer dependency ranges remain as explicit compatible majors (using `^X.Y.Z`).
+Breaking change: move ESLint core and all ESLint plugin/config packages from `dependencies` to `peerDependencies`. Consumers must now install these directly in their projects to use this shared config:
+
+- `eslint`
+- `@typescript-eslint/parser`
+- `@typescript-eslint/eslint-plugin`
+- `eslint-config-xo-typescript`
+- `eslint-plugin-import`
+- `eslint-import-resolver-typescript`
+- `eslint-plugin-unicorn`
+- `eslint-plugin-sonarjs`
+- `eslint-plugin-unused-imports`
+
+Also align this package’s `devDependencies` with the exact versions resolved in the workspace lockfile to support local development of the config.
