feat: Glitch Detector HTML Report with annotated screenshots #544

Replaces 12-line stub with full 3D world glitch detector + HTML report.

Features:
- Programmatic pixel analysis (render failure, tearing, brightness)
- Vision model analysis (Gemma 3) for 8 glitch types
- Standalone HTML report with inline CSS, no external deps
- Score gauge, severity dots, screenshot thumbnails
- Batch mode for multi-screenshot analysis
- JSON + text output formats

Glitch types: floating_asset, z_fighting, texture_pop, clipping,
lighting, mesh_break, render_failure, ui_overlap

HTML report includes:
- Overall verdict badge (PASS/WARN/FAIL)
- Score gauge (SVG circle)
- Per-screenshot cards with inline base64 screenshots
- Glitch list sorted by severity with confidence scores

Tests: 13/13 passing.
Closes #544

+matrix_glitch_detect.py — 3D World Visual Artifact Detection for The Matrix.
+
+Scans screenshots or live pages for visual glitches: floating assets, z-fighting,
+texture pop-in, clipping, broken meshes, lighting artifacts. Outputs structured
+JSON, text, or standalone HTML report with annotated screenshots.
+
+Usage:
+    # Scan a screenshot
+    python scripts/matrix_glitch_detect.py --image screenshot.png
+
+    # Scan with vision model
+    python scripts/matrix_glitch_detect.py --image screenshot.png --vision
+
+    # HTML report
+    python scripts/matrix_glitch_detect.py --image screenshot.png --html report.html
+
+    # Scan live Matrix page
+    python scripts/matrix_glitch_detect.py --url https://matrix.alexanderwhitestone.com
+
+    # Batch scan a directory
+    python scripts/matrix_glitch_detect.py --batch ./screenshots/ --html batch-report.html
