🧹 refactor(arch): optimize agentic-architecture and microkernel-architecture for deterministic Agent parsing

[beginwebdev2002]

Refactored agentic-architecture and microkernel-architecture documentation to follow strict architectural boundaries and rules, ensuring proper modularization by splitting large readmes into explicit data-flow.md, folder-structure.md, implementation-guide.md, and trade-offs.md files while adhering to the standard 4-step lifecycle and Mermaid blueprint guidelines.
