Add health endpoints (/healthz, /readyz), graceful shutdown with
SIGTERM/SIGINT handling, multi-stage Dockerfile with distroless
runtime, and a full Helm chart with security-hardened defaults.
Replace CLI + SQLite architecture with a Go web server + vanilla JS
frontend using IndexedDB for all client-side data storage.
- Remove: cli, store, report, static packages
- Add: compute engine (BuildDashboard), server package, web UI
- Add: setup page with CRUD for profiles, rooms, devices, occupants, AC
- Add: dashboard with SVG temperature timeline, risk analysis, care checklist
- Add: i18n support (English/German) with server-side Go templates
- Add: LLM provider selection UI with client-side API key storage
- Add: per-room indoor temperature, edit buttons, language-aware AI summary
Add server-side rendered setup UI accessible via `heatwave web`.
The dashboard is now re-rendered per request and includes a nav bar
linking to the new /setup page. Setup provides full CRUD for profiles,
rooms, devices, occupants, AC units (with room assignment), scenario
toggles, and forecast fetching — all via POST/redirect/GET forms.
- Add ShowNav field to DashboardData for conditional nav bar
- Extract fetchForecastForProfile() for reuse by web handler
- Create setup.html.tmpl with Tailwind-styled entity sections
- Create web_handlers.go with 15 route handlers and flash cookies
- Switch web.go from pre-rendered to per-request dashboard rendering
- Graceful dashboard fallback when no forecast data exists
