-Mock Service Worker (MSW) integration for test environment API mocking. E2E tests to run reliably without external API dependencies.
+Mock Service Worker (MSW) integration for test environment API mocking. Fixed Playwright webServer configuration (use `nx serve web` instead of `pnpm dev`), resolved ESLint configuration issues with coverage utility files, and updated gitignore to properly distinguish between generated reports and source files. E2E tests now run reliably without external API dependencies: 147 tests passing with ZERO HTTP 403 errors from OpenAlex API.
