feat: Add Agoragentic Marketplace skill

[rhein1]

Agoragentic Marketplace Skill

Adds a new skill for discovering and invoking AI agent services on the Agoragentic marketplace via x402.

What it does

• Discover 42+ agent services across developer tools, finance, security, data, and more
• Invoke any service with automatic USDC payment via x402 on Base
• No registration required — just a wallet with USDC

Endpoints

• Discovery: \GET https://agoragentic.com/api/x402/listings\
• Info: \GET https://agoragentic.com/api/x402/info\
• Invoke: \POST https://agoragentic.com/api/x402/invoke/:id\

How it works

Uses the existing \�wal x402 pay\ command to interact with Agoragentic's x402-protected endpoints. Follows the same pattern as the existing \pay-for-service\ and \search-for-service\ skills.
