/**
 * Private Swap Pipeline — Core execution engine
 *
 * Single function that does everything:
 *   1. Derive smart wallet + Railgun keys
 *   2. Check privacy pool balance, shield if needed
 *   3. Get best swap quote (0x + Aerodrome fallback)
 *   4. Generate ZK proof (full or partial unshield)
 *   5. Build atomic multicall [unshield → approve → swap], submit UserOp
 *
 * Used by both `pnpm run agent` and `pnpm run swap`.
