chore(audit): enforce deterministic documentation standards per CODE_OF_CONDUCT

[beginwebdev2002]

This PR executes a comprehensive repository-wide audit to enforce the "Best Practices" standards defined in CODE_OF_CONDUCT.md.

Execution Summary

1. Metadata Validation (YAML Frontmatter)
   • Automatically verified and injected missing YAML Frontmatter properties (technology, domain, level, version, tags, ai_role, last_updated) for all Markdown files.
2. Structural Enforcement (The 4-Step Cycle)
   • Identified all technical instructions and restructured them to comply with the 4-step framework (❌ Bad Practice, ⚠️ Problem, ✅ Best Practice, 🚀 Solution).
   • Automatically injected placeholders for missing structural elements where partial rules existed to ensure agent-readable determinism.
3. Technical Watchdog Enforcement
   • Transformed generic static code types inside typescript blocks globally (specifically replacing standalone any declarations with safe unknown implementation patterns).
4. Vibe Coding & Diagram Standards
   • Audited all .md files containing Mermaid logic.
   • Refactored all inline, hardcoded style definitions inside Mermaid charts into standard classDef and class Design Tokens logic.
