Phase 1: scaffold Next.js 16 web-ui + Coolify staging

- create-next-app with TypeScript, Tailwind v4, App Router
- Port design-system.css tokens into Tailwind @theme (navy/gold/parchment, Heebo)
- Install TanStack Query, react-hook-form, zod, lucide-react, react-dropzone
- layout.tsx: RTL Hebrew + Heebo via next/font/google
- AppShell component with navy header + gold rule + nav
- next.config.ts: output:standalone + rewrites to proxy /api/* to production FastAPI
- Dockerfile: multi-stage Node 20 Alpine build for Next.js standalone
  (branch-local override of the FastAPI Dockerfile; main is unaffected)
- Switch .taskmaster to claude-code provider (no API key required)
- Add 7 phase tasks (83-89) tracking the full rewrite plan

+# Dockerfile — Next.js 16 web-ui (ui-rewrite branch only)
+#
+# This file REPLACES the FastAPI Dockerfile on this branch so that
+# Coolify's default /Dockerfile lookup builds the new Next.js staging
+# UI. The FastAPI Dockerfile lives on `main` and is unaffected.
+#
+# When the rewrite is merged to main, decide between:
+#   (a) keeping both via separate Dockerfiles + dockerfile_location config, or
+#   (b) a multi-stage Dockerfile that serves both, or
+#   (c) fully replacing FastAPI's StaticFiles with this Next.js front end.
