feat: Add storage skill, add OWS to wallets

[1a35e1]

Summary

• New storage/ skill — IPFS pinning, Arweave permanence, x402 payments for storage, ENS contenthash hosting
• OWS added to wallets/ — Open Wallet Standard for encrypted local wallet signing in agent workflows (Web3 Secret Storage keystore standard)
• Storage skill added to root index

Blind spots filled (🔴)

• IPFS does NOT store files permanently — need a pinning service
• Arweave does NOT use content addressing — txIds are from signatures, not content
• ENS websites use onchain contenthash (EIP-1577), not URL text records
• x402 enables agents to pay for IPFS/Arweave storage inline with HTTP requests
• Open Wallet Standard exists — encrypted local wallets for CLI/agent signing using Web3 Secret Storage keystore format
• Infura IPFS was deprecated (Nov 2025)
• web3.storage pivoted to Filecoin-only

Human needs to learn (🟣)

• Storage tier tradeoffs (CDN vs IPFS vs Arweave)
• How ENS contenthash hosting works end-to-end
• OWS as a safer alternative to .env files for agent key management
