✅ Testing

• VuePress builds successfully
• GitHub Actions workflow validated
• Documentation sync workflow need to be tested

⚠️ Note

This PR provides the foundation skeleton for the workflow proposed in #2. The VuePress setup is functional but requires further development:

• Design & Styling: Current styling is minimal and needs visual improvements
• Content: Documentation content is basic and requires review/enhancement
• UX: User experience and navigation need refinement
• Branding: Edge Mining visual identity needs to be properly implemented

This foundation enables immediate automated publishing while providing a solid base for future design and content improvements.
