Subject: [PATCH] Full sweep: fix broken features, redesign NodePreview, wire
 AI service
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

FIXES (from comprehensive audit):
- NodePreview: complete rewrite — 380px left panel with document
  summaries, commitment list, phase track visualization, scrollable.
  Fixed children count bug (was showing [object Object]).
  Slides in from left (not right) to not overlap branch handles.
- CommitmentForm: added required validation on eigenaar_id field
- MetroMap: wired custom metro node creation with form + POST /metro-nodes
- MetroMap: removed dead handleCliCommand console.log
- MetroMap: added metro node creation modal (naam + beschrijving)

NEW — AI Service integration:
- ai-service/main.py: real Anthropic API integration via httpx
  - Reads ANTHROPIC_API_KEY from env, uses claude-haiku-4-5-20251001
  - /api/chat fetches project context from PostgreSQL (docs, commitments)
  - /api/summarize sends content to Claude for summarization
  - /api/search does basic text search on documents + kennis_artikelen
- AiController.php: Laravel proxy for /api/ai/chat → ai-service
- CliBar.vue: complete rewrite with async API calls, processing state,
  error handling, conversation history, auto-scroll
  - Receives projectId prop for context-scoped AI queries
  - Shows "denken..." animation while waiting for response
- docker-compose.yml: passes ANTHROPIC_API_KEY to ai-service container
- config/services.php: ai service URL configuration

To activate AI: set ANTHROPIC_API_KEY in .env and rebuild ai-service.
