[docs: autonomous-visual-synthesis] Inject structural classDiagrams

[beginwebdev2002]

This pull request performs autonomous visual synthesis according to the rules of the operational algorithm. It scans for markdown files that contain "Component Relations (Folder structure text blocks)" and injects proper Mermaid classDiagram visualizations immediately after them, using exact classDef styling tokens. Duplicate component nodes within folder hierarchies are avoided by ensuring each structural entity maps uniquely while maintaining relationships.

Pre-commit verification scripts (vibe-check-runner.js, generate-sitemap.js, and commit_verify.py) were run to ensure code validation and safe structural changes.
