Add comprehensive automated testing script

- Validates build (content.js format, files, manifest)
- Checks TypeScript compilation
- Runs unit tests (non-blocking warnings)
- Validates critical code paths (window checks, storage usage)
- Can be run with: npm run test:all
- Prevents asking user to test until build is validated
