Introduce Lecture 14 (From Single Loops to Graph Engineering) and Project 08
(Draw Your Workflow as a Graph), translated into all 15 locales. Update the
sidebar config, per-locale READMEs (what's-new blocks, learning path phases
7-8, project evolution, and outline links pointing to each locale's docs),
and the root/zh-CN READMEs.
Key content: the four stacked layers (prompt to context to loop to graph) and
where harness sits, the four parts of a graph, why in-loop checkpoints can't
fix the three structural failures at scale, a framework-agnostic six-step
build walkthrough, graph vs. workflow, anchors, and the open-source
landscape before vs. after the name.
