feat: add comprehensive frontend testing infrastructure
Add Jest unit tests and Playwright E2E tests for critical frontend components, focusing on the notification system and countdown timers. Testing Infrastructure: - Jest unit tests with jsdom for browser API simulation - Playwright E2E tests for multi-browser testing - Test utilities for mocking notifications, localStorage, and timers - Coverage thresholds: 80% lines, 75% functions, 70% branches Performance Optimizations: - Add _config.test.yml for 10-15 second Jekyll startup (vs 60-90s production) - Configure incremental builds and minimal plugin loading - Provide npm scripts for different server configurations CI/CD Integration: - GitHub Actions workflows for automated testing on push/PR - Coverage reporting with Codecov integration - PR comments with test results summary - Daily scheduled regression tests Test Coverage: - Notification system: permission flow, deadline alerts, toast notifications - Countdown timers: real-time updates, timezone handling, performance - Conference management: favoriting, dashboard, action bar - Cross-browser and mobile compatibility
