E2E Production Benchmark: Tests all live Lux services against public endpoints.

Validates:
  1. Blockchain RPC (Lux C-Chain + Zoo mainnet)
  2. Explorer APIs (all 5 chains via Blockscout)
  3. MPC service availability
  4. Bridge API health
  5. Exchange frontend
  6. Cross-chain connectivity (Lux <-> Zoo)

Usage:
