feat: implement v0.4.0 - Reports, Charts, Comparison, Dark Mode, E2E Testing
Backend (@backend-dev): - Add ReportService with PDF/CSV generation (reportlab, pandas) - Implement Report API endpoints (POST, GET, DELETE, download) - Add ReportRepository and schemas - Configure storage with auto-cleanup (30 days) - Rate limiting: 10 downloads/minute - Professional PDF templates with charts support Frontend (@frontend-dev): - Integrate Recharts for data visualization - Add CostBreakdown, TimeSeries, ComparisonBar charts - Implement scenario comparison page with multi-select - Add dark/light mode toggle with ThemeProvider - Create Reports page with generation form and list - Add new UI components: checkbox, dialog, tabs, label, skeleton - Implement useComparison and useReports hooks QA (@qa-engineer): - Setup Playwright E2E testing framework - Create 7 test spec files with 94 test cases - Add visual regression testing with baselines - Configure multi-browser testing (Chrome, Firefox, WebKit) - Add mobile responsive tests - Create test fixtures and helpers - Setup GitHub Actions CI workflow Documentation (@spec-architect): - Create detailed kanban-v0.4.0.md with 27 tasks - Update progress.md with v0.4.0 tracking - Create v0.4.0 planning prompt Features: ✅ PDF/CSV Report Generation ✅ Interactive Charts (Pie, Area, Bar) ✅ Scenario Comparison (2-4 scenarios) ✅ Dark/Light Mode Toggle ✅ E2E Test Suite (94 tests) Dependencies added: - Backend: reportlab, pandas, slowapi - Frontend: recharts, date-fns, @radix-ui/react-checkbox/dialog/tabs - Testing: @playwright/test 27 tasks completed, 100% v0.4.0 implementation
