Add a page to showcase Hub's AI capabilities

[im-adithya]

Needs design + planning

Ideas:

• Configuring OpenClaw using sats (inspiration)
• Spawning child bots (article)
• AI Skills section (builder + wallet skills + MCP)
• Mini Video Demos of configured agents
• Showcase Alby Sandbox and lncurl?

• Would featured apps be a solution?
• What about a landing page for agentic payments and why Alby Hub is a great choice? does our current AI page cover everything we want to show? Does it fit a user that just wants to give a wallet to their OpenClaw? (LNVPS+PPQ+LNEmail+unhuman domains etc)
• Consider a blog post and possibly link to it from the landing page
