style(ci): add action emojis to workflow names for visual scanning

Add separator and action-specific emojis to make it easier to visually
distinguish between workflow types (Build/Publish/Validate) at a glance.

Pattern: Category emoji + Name · Action emoji + Action
- 🔨 Build
- 📤 Publish
- 🔍 Validate
- 🐳 Container
- 🧹 Cleanup
- 🔗 Link Check
- ❤️ Health Check
