feat: add CV inspection overlay with visual effects

- Add CVInspectionOverlay component (industrial camera monitor style)
- Add inspectionViewModel adapter for playback → inspection data
- Add camera rig with overhead frame and laser emitters
- Add inspection zone highlight on belt
- Add animated scan line during detection
- Add bounding box wireframe during measurement
- Add shape outline (circle/square) during classification
- Show dimensions pass/fail, roundness warning, confidence warning
- Show C-priority indicator for edge cases

+# CV Inspection Overlay Report
+
+**Date:** 2026-07-09  
+**Status:** Implemented
+
+---
+
+## What Was Added
+
+### 1. CV Inspection Overlay (`src/components/CVInspectionOverlay.tsx`)
+
+Industrial camera monitor style panel showing:
+- Item title
+- Detected shape (box / cylinder / round / irregular)
+- Dimensions (W × D × H mm) with pass/fail indicator
+- Roundness K value with ≥0.7 warning
+- Confidence % with LOW warning
+- Classification result (B/C/D)
+- Command (ROUTE_TO_*)
+- Warning messages (low confidence, C priority)
+
+### 2. Inspection View Model (`src/domain/inspectionViewModel.ts`)
+
+Data adapter providing:
+- `InspectionData` interface
+- Phase-based visibility logic
+- Dimension fail detection
+- Roundness fail detection
+- C-priority indicator
+
+### 3. 3D Visual Effects (in `SorterDigitalTwinContinuous.tsx`)
+
+**Camera Rig:**
+- Overhead frame with cross beam
+- Support poles
+- Camera unit with lens
+- Laser emitters on sides
+- Active highlight when detecting
+
+**Inspection Zone:**
+- Rectangle on belt under camera
+- Corner markers
+- Active highlight
+
+**Scan Line:**
+- Animated cyan line sweeping across detection zone
+- Only visible during detection phase
+
+**Bounding Box:**
+- Wireframe around item during measurement
+- Dimension lines (dashed)
+
+**Shape Outline:**
+- Circle for round items (D category)
+- Square for box items (B/C)
+- Colored by category
+
+---
+

+
+## Phase Display
+
+| Phase | CV Overlay | 3D Effects |
+|-------|-----------|------------|
+| spawn | Hidden | — |
+| move_to_detection | Hidden | — |
+| detection | "Detecting object" | Camera active, scan line |
+| measurement | "Measuring dimensions" | Camera active, bounding box |
+| classification | "Classifying" | Shape outline |
+| command_sent | "Command sent" | Shape outline |
+| routing | "Routing to zone" | Route highlight |
+| exit | Hidden | — |
+| clear_gap | Hidden | — |

+
+### Key Screenshots
+
+**inspection_detection.png:**
+- Camera rig visible
+- CV overlay shows "Measuring dimensions"
+- Dimensions displayed: 300 × 200 × 200 mm (green = pass)
+
+**c_priority_inspection.png:**
+- Case 7: "Негабарит + круглый"
+- SIZE: 500 × 300 × 300 mm (red = fail)
+- ROUNDNESS: 0.93 (red = ≥0.7)
+- CLASS: C (C priority) — correct priority over D
+
+**low_confidence_warning.png:**
+- Case 8: "Low confidence fallback"
+- CONFIDENCE: 58% LOW (orange warning)
+- Warning: "Low confidence is a warning, not a 4th category"
+- CLASS: B (rule-based still works)

+curl -I https://arhipovdan.ru/details → 200 OK
+```
+
+**Browser QA:**
+- ✓ CV overlay visible during inspection
+- ✓ Camera rig renders correctly
+- ✓ Scan line animates
+- ✓ Bounding box appears
+- ✓ Shape outline visible
+- ✓ Dimensions pass/fail highlighted
+- ✓ Roundness warning shown
+- ✓ Low confidence warning shown
+- ✓ C-priority indicator works
+- ✓ No console errors
+
+---
+
+## Build/Test Results
+
+```
+✓ npm run build — success
+✓ npm run test — 59 tests passed
+✓ docker rebuild — success
+```
+
+---
+
+## What Remains
+
+- Fine-tune scan line animation speed
+- Optional: Add laser beam visualization
+- Optional: Camera view-in-view widget
