Add document converter, seeder data structure, and project wiki

- ai-service/convert.py: converts Office/PDF files to markdown with frontmatter
- database/seeders/data/: folder structure for themas, projects, documents, etc.
- database/seeders/data/raw/: drop zone for Office/PDF files to convert
- wiki/: project architecture, concepts, and knowledge graph documentation
- Remove unused Laravel example tests

+# Metro Map UI Architecture
+
+The entire platform navigates via a **zoomable metro/transit map**. No sidebar, no traditional dashboard. Users explore the innovation landscape visually.
+
+## Map Levels
+
+| Level | What You See | Lines = | Stations = | Zoom Target |
+|---|---|---|---|---|
+| 1. Strategy | Full innovation landscape | Strategic themes (Thema) | Projects | Click station → Level 2 |
+| 2. Project | Single project lifecycle | Lifecycle + Commitments + Documents | Phases, items | Click station → Level 3 |
+| 3. Detail | Individual item | (not yet implemented) | — | Click to open |
+
+## Technical Implementation
+
+### MetroCanvas.vue (356 LOC)
+
+- **Rendering**: D3.js 7.9 on SVG
+- **Zoom**: `d3.zoom()` with `scaleExtent([0.3, 5])`, pan + zoom
+- **Lines**: `d3.curveMonotoneX` paths connecting stations
+- **Stations**: Two concentric circles (outer ring = line color, inner dot = status color)
+- **Labels**: VT323 monospace font, positioned below stations
+- **Interactions**: hover → glow effect + tooltip, click → emit node-click
+- **Dependencies**: Dashed lines between connected stations across lines
+
+### Data Contract (MapDataService → MetroCanvas)
+
+```json
+{
+  "lines": [
+    { "id": "thema-1", "name": "Waterkwaliteit", "color": "#00d2ff" }
+  ],
+  "nodes": [
+    {
+      "id": "project-1",
+      "entityId": 1,
+      "entityType": "project",
+      "name": "Sensor Netwerk",
+      "lineId": "thema-1",
+      "x": -200, "y": 0,
+      "order": 1,
+      "status": "verkenning",
+      "description": "...",
+      "owner": "Jan",
+      "badge": "Verkenning",
+      "children": 5
+    }
+  ],
+  "connections": [
+    { "from": "project-1", "to": "project-3" }
+  ],
+  "level": 1
+}
+```
+
+### Station Status Colors
+
+| Status | Color | Hex |
+|---|---|---|
+| afgerond / completed | Neon green | `#00ff88` |
+| actief / active | Vivid cyan | `#00d2ff` |
+| geparkeerd | Warning yellow | `#ffd93d` |
+| gestopt | Signal red | `#e94560` |
+| default (pending) | Dark fill | `#16213e` |
+
+### Visual Effects
+
+- **Glow filter**: SVG `feGaussianBlur` with `stdDeviation=4`, applied on hover
+- **Scanline pattern**: 4px repeating lines at 8% opacity (subtle CRT effect)
+- **Hover transition**: 200ms radius 8→12 + glow filter
+- **Zoom animation**: 500ms d3 zoom transition for `zoomTo()` method
+
+## C64 CLI Bar (CliBar.vue)
+
+Fixed at bottom of screen. Commodore 64 aesthetic:
+- Monospace font (Press Start 2P / VT323)
+- Blinking block cursor
+- Dark background, cyan/green text
+- Natural language input
+- Responses slide up above bar with `[AI]` prefix
+
+## Design System
+
+### Color Palette
+
+| Role | Hex | Usage |
+|---|---|---|
+| Background | `#1a1a2e` | Canvas, page background |
+| Surface | `#16213e` | Cards, tooltips, panels |
+| Primary | `#0f3460` | Metro lines, primary actions |
+| Accent (cyan) | `#00d2ff` | Active states, highlights, CLI cursor |
+| Accent (red) | `#e94560` | Warnings, deadlines |
+| Accent (green) | `#00ff88` | Success, completed |
+| Accent (purple) | `#7b68ee` | Knowledge, documentation |
+| Text primary | `#e8e8e8` | Main text |
+| Text secondary | `#8892b0` | Labels, secondary text |
+
+### Fonts
+
+| Use | Font | Fallback |
+|---|---|---|
+| Map labels | VT323 | monospace |
+| CLI bar | Press Start 2P | VT323, monospace |
+| Body text | IBM Plex Sans | Inter, sans-serif |
+| Code | IBM Plex Mono | monospace |
+
+## Planned Enhancements
+
+- **Zoom-to-dimension**: scroll-zoom near a station gradually cross-fades into child dimension (no click needed)
+- **Recursive dimensions**: every node can contain children forming a sub-metro-map, infinitely nestable
+- **Right-click context menu**: canvas = "New node here", station = "Edit/Delete/Add child"
+- **[+] FAB**: creates at current depth
+- **Mobile**: list fallback with metro line colors preserved
