- Add canPushToCommunity() to check quality requirements
- Show Push to Community button for non-public configs
- Button enabled if config meets criteria (5+ packages, custom name, description)
- Button disabled with tooltip if quality threshold not met
- One-click promotion to Explore page
- Success toast notification after pushing
- Helps users discover and share high-quality configs
