packages/eslint-plugin-final/src/finalPlugin.ts:7

• Same issue as in src/index.ts: importing ./finalPluginUtils.js from TypeScript source while using moduleResolution: "Node" can break compilation because TS may not resolve .js specifiers to .ts files. Align the tsconfig module resolution (Node16/NodeNext/Bundler) or drop the .js extension in the source import specifier.
