- Add exclude: ['e2e/**', 'node_modules/**'] to vitest.config.ts test block
to prevent Playwright specs from being picked up by Vitest jsdom runner
- Add tsconfig.e2e.json extending main tsconfig with node types for
playwright.config.ts and e2e/**/* typecheck coverage
- Add @types/node to pwa devDependencies (required by playwright.config.ts)
- Update typecheck script to run both src and e2e tsc passes
- 191 unit tests still pass; no e2e import errors in vitest run
