Unified Tool Registry - accurate count of ALL tools across the system.

  - X402 gateway tools (CF Workers)
  - Our MCP server tools (mcp_server.py)
  - Local MCP servers (SVM 60+ tools, EVM 25 tools)
  - Service MCP (GMGN, Birdeye, Solscan, CoinGecko, Etherscan, Moralis: 13 tools)
  - Caching shield data providers (6 chains, 20+ providers)
  - Free external MCP servers (Boar 50 tools)
  - Investigative framework endpoints
