feat: Multimodal Visual PR Review Tool #495

Replaces 11-line stub with full visual QA tool. Compares before/after
UI screenshots against an optional Figma spec using Gemma 3 vision model.

Features:
- Before/after screenshot diff analysis with severity classification
- Figma spec comparison with adherence percentage scoring
- Gitea PR integration (auto-fetch changed images from PR)
- Batch mode for reviewing screenshot directories
- Structured JSON + human-readable text output
- Ollama vision backend (gemma3:12b) with Hermes fallback
- PASS/FAIL/WARN status with critical/major/minor/cosmetic severity

CLI:
  visual_pr_reviewer.py --before b.png --after a.png
  visual_pr_reviewer.py --before b.png --after a.png --spec figma.png
  visual_pr_reviewer.py --repo owner/repo --pr 123
  visual_pr_reviewer.py --batch ./screenshots/

Tests: 10/10 passing.
Closes #495

-nexus_smoke_test.py — Visual Smoke Test for The Nexus.
-
-Takes screenshots of The Nexus landing page, verifies layout consistency
-using both programmatic checks (DOM structure, element presence) and
-optional vision model analysis (visual regression detection).
-
-The Nexus is the Three.js 3D world frontend at nexus.alexanderwhitestone.com.
-This test ensures the landing page renders correctly on every push.
-
-Usage:
-    # Full smoke test (programmatic + optional vision)
-    python scripts/nexus_smoke_test.py
-
-    # Programmatic only (no vision model needed, CI-safe)
-    python scripts/nexus_smoke_test.py --programmatic
-
-    # With vision model regression check
-    python scripts/nexus_smoke_test.py --vision
-
-    # Against a specific URL
-    python scripts/nexus_smoke_test.py --url https://nexus.alexanderwhitestone.com
-
-    # With baseline comparison
-    python scripts/nexus_smoke_test.py --baseline screenshots/nexus-baseline.png
-
-Checks:
-    1. Page loads without errors (HTTP 200, no console errors)
-    2. Key elements present (Three.js canvas, title, navigation)
-    3. No 404/error messages visible
-    4. JavaScript bundle loaded (window.__nexus or scene exists)
-    5. Screenshot captured successfully
-    6. Vision model layout verification (optional)
-    7. Baseline comparison for visual regression (optional)

-"""
-tower_visual_mapper.py — Holographic Map of The Tower Architecture.
-
-Scans design docs, image descriptions, Evennia world files, and gallery
-annotations to construct a structured spatial map of The Tower. Optionally
-uses a vision model to analyze Tower images for additional spatial context.
-
-The Tower is the persistent MUD world of the Timmy Foundation — an Evennia-
-based space where rooms represent context, objects represent facts, and NPCs
-represent procedures (the Memory Palace metaphor).
-
-Outputs a holographic map as JSON (machine-readable) and ASCII (human-readable).
-
-Usage:
-    # Scan repo and build map
-    python scripts/tower_visual_mapper.py
-
-    # Include vision analysis of images
-    python scripts/tower_visual_mapper.py --vision
-
-    # Output as ASCII
-    python scripts/tower_visual_mapper.py --format ascii
-
-    # Save to file
-    python scripts/tower_visual_mapper.py -o tower-map.json
-

+
+Compares 'before' and 'after' screenshots of a UI change against an optional

+
+    # Compare against a Figma spec
+    python scripts/visual_pr_reviewer.py --before before.png --after after.png --spec figma.png
+
+    # Review all changed HTML/CSS in a PR branch
+    python scripts/visual_pr_reviewer.py --repo Timmy_Foundation/the-beacon --pr 116
+
+    # Batch review a directory of screenshot pairs
+    python scripts/visual_pr_reviewer.py --batch ./screenshots/
