Add skill: philidor — DeFi vault intelligence

[zkoranges]

Summary

Adds the philidor skill — a DeFi vault intelligence toolkit for risk scores, yield comparison, portfolio analysis, and oracle monitoring.

• What it does: Provides CLI commands for searching DeFi vaults, comparing yields and risk, analyzing wallet portfolios, and monitoring oracle freshness across Morpho, Yearn, Aave, Beefy, and Spark on 6 chains (Ethereum, Base, Arbitrum, Polygon, Optimism, Avalanche).
• Who uses it: DeFi analysts, portfolio managers, risk teams, and AI agents that need to evaluate vault safety before recommending yield opportunities.
• How it works: The CLI (@philidorlabs/cli on npm) calls the public Philidor API at api.philidor.io. No API key required.
