feat(skills): add baoyu-infographic skill — 21 layouts × 21 styles

Port of baoyu-infographic from JimLiu/baoyu-skills (v1.56.1) adapted
for Hermes Agent's tool ecosystem.

Adaptations from upstream:
- Frontmatter: openclaw metadata → hermes metadata
- Usage: slash command syntax → natural language triggers
- Removed EXTEND.md config system (not part of Hermes infrastructure)
- AskUserQuestion → clarify tool (one question at a time)
- Image generation → image_generate tool
- Removed Windows-specific paths
- Simplified file operations to use Hermes file tools
- All 45 reference files (layouts, styles, templates) preserved intact

Attribution preserved per agreement with 宝玉 (Jim Liu):
- author, version, GitHub homepage URL in frontmatter
