docs(ms-ai-architect): add v1.11.0 sections to README + CHANGELOG
- README.md: new "v1.11.0 — Design-system 100%-adoption" section under
Playground (v3), parallel to existing v1.10.0 Foundation refactor
section. Documents hoisted DS components, PARALLEL CSS migration,
inline style trim, visual upgrade benchmarks, and intentional
plugin-local survivors.
- CHANGELOG.md: new [1.11.0] entry with Added subsection, plugin-local
survivors note, and 3-session rollout note. Tests baseline 278 PASS.
Follow-up to release commit 7ffaa82 — release was pushed without these
deeper doc sections.
