docs(arch): autonomous evolution of architecture blueprints for deterministic Agent parsing

[beginwebdev2002]

This PR autonomously evolves the ./architectures/ directory to act as a deterministic blueprint layer for AI agents.

Key structural changes:

• Standardized the mandatory YAML frontmatter (technology, domain, level, version, tags, ai_role, last_updated) across all markdown files.
• Dynamically injected the "Map of Patterns" into the root architectures/readme.md for proper bi-directional linking.
• Added the mandatory 4-step execution cycle (❌ Bad Practice, ⚠️ Problem, ✅ Best Practice, 🚀 Solution) to the DDD and Monolithic architecture implementation-guide.md files where it was missing.
