feat: V2 重制 9 个演示 GIF + 新增英文版 + hero 升级到 v10

亮点：
- 统一 VI：全部对齐 hero-v10 色板 (#000000 + #D97757) 和 Brand Reveal 米色面板 signature
- 文字克制：每个 demo 控制在 20-48 字 / 15-36 词，从解释性文字转为锚点
- 中英平行：英文版不是字幕翻译，画面元素重新设计
- 高清 GIF：1280×720 · 25fps · full palette · sierra2_4a dither
- Concept-driven：每个 demo 都有清晰的核心传达隐喻，哑剧测试可过

文件变更：
- 9 个能力/流程 demo 全部 V2 重做（c1-c6, w1-w3），中英双版
- hero animation 从 v9 升级到 v10（中英双版）
- README.md 引用更新 v9 → v10
- README.en.md 所有 GIF 加 -en 后缀 + note 更新
- 移除冗余：20 个 -60fps.mp4（README 未引用）+ 18 个 demo MP4

The skill's agent prompts (`SKILL.md`, `references/*.md`) and all demo assets below are in **Chinese** — they work with English tasks just fine (the agent is bilingual), but the visible text in screenshots/GIFs is Chinese. The core design principles translate universally.

 ### Design Direction Advisor
 
 The fallback for vague briefs: pick 3 differentiated directions from 5 schools × 20 philosophies, generate all 3 demos in parallel, let the user choose.

 ### Motion Design Engine
 
 Stage + Sprite time-slice model · `useTime` / `useSprite` / `interpolate` / `Easing` — four APIs cover every animation need · one command exports MP4 / GIF / 60fps-interpolated / BGM-scored finals.

 ### Junior Designer Workflow
 
 No heroic one-shot attempts: start with assumptions + placeholders + reasoning, show it to the user early, then iterate. Fixing a misunderstanding early is 100× cheaper than fixing it late.

 ### Core Asset Protocol · 5-step hard process
 
 Mandatory whenever the task involves a specific brand: ask → search → download (three fallback paths) → verify + extract → write `brand-spec.md` covering **logo, product shots, UI screenshots, colors, fonts** — all required assets, not just colors.
