Hyperliquid Account Balance & Equity

Read a Hyperliquid account's balance and equity from its clearinghouse / user state: account value (total equity), available margin, and used margin (marginSummary), plus withdrawable balance. Also returns active perp positions (each with its own unrealized PnL), resting open orders, and HIP-4 outcome token holdings. Set `balanceOnly: true` for a cheap equity/balance read that skips position aggregation (positions, open orders and outcome holdings come back empty). Ideal for: live-equity position sizing, portfolio monitoring, risk and margin-health checks, and pre-trade balance gates.
