report(1H): add Agentic Workloads (§6) and HW-Spec Search (§7) sections

- §6 Supporting Agentic Workloads: how the fused GQA design extends to
  agentic fan-out/fan-in; three-layer split (framework/runtime/kernel);
  Stationary-KV vs Distributed-Q execution policies.
- §7 Hardware Performance-Spec Search for GQA: WIP stub (sweep intent
  over GEMM TFLOPS, MATH-engine ALUs, CUBE↔CUBE and SIP↔SIP BW).
- Renumber Discussion/Conclusion/Future-Work to 08/09/10; update
  main.tex input order and toc.md.
- Add Agentic_Runtime_Architecture.md design note; rebuild main.pdf.
