docs(frontend): autonomous architectural standardization for multiple technologies

[beginwebdev2002]

Standardized the frontend documentation to ensure strict deterministic consistency for AI Agents:

• Updated the YAML frontmatter across angular, react, typescript, qwik, solidjs, and javascript directories to include only the requested fields: technology, domain, level, version, tags, ai_role, and last_updated.
• Adjusted versions for specific technologies (e.g., Angular to 20+, React to 19+, TypeScript to 5.5+).
• Refactored all instruction lifecycles to consistently use exactly: ### ❌ Bad Practice, ### ⚠️ Problem, ### ✅ Best Practice, and ### 🚀 Solution across all files in the frontend knowledge layer.
