feat: Add Hyperliquid exchange support with unified trader interface

Major changes:
- Add full Hyperliquid trading support (long/short, leverage, SL/TP)
- Create unified Trader interface for multi-exchange support
- Implement automatic precision handling for orders and prices
- Fix balance calculation and unrealized P&L display
- Add comprehensive configuration guide in README

New features:
- Support for both Binance and Hyperliquid exchanges
- Automatic order size precision based on szDecimals
- Price formatting with 5 significant figures
- Non-custodial trading with Ethereum private key
- Seamless exchange switching via configuration

Technical details:
- Add trader/interface.go for unified trader interface
- Add trader/hyperliquid_trader.go for Hyperliquid implementation
- Update manager and auto_trader to support multiple exchanges
- Add go-hyperliquid SDK dependency
- Fix precision errors (float_to_wire, invalid price)

Fixes:
- Correct calculation of wallet balance and unrealized P&L
- Proper handling of AccountValue vs TotalRawUsd
- Frontend display issues for total equity and P&L

Documentation:
- Add Hyperliquid setup guide in README
- Update config.json.example with both exchanges
- Add troubleshooting section for common errors

Tested with live trading on Hyperliquid mainnet.
No breaking changes - backward compatible with existing configs.

+#### 🔷 Alternative: Using Hyperliquid Exchange
+
+**NOFX also supports Hyperliquid** - a decentralized perpetual futures exchange. To use Hyperliquid instead of Binance:
+
+**Step 1**: Get your Ethereum private key (for Hyperliquid authentication)
+
+1. Open **MetaMask** (or any Ethereum wallet)
+2. Export your private key
+3. **Remove the `0x` prefix** from the key
+4. Fund your wallet on [Hyperliquid](https://hyperliquid.xyz)
+
+**Step 2**: Configure `config.json` for Hyperliquid
+
+```json
+{
+  "traders": [
+    {
+      "id": "hyperliquid_trader",
+      "name": "My Hyperliquid Trader",
+      "ai_model": "deepseek",
+      "exchange": "hyperliquid",
+      "hyperliquid_private_key": "your_private_key_without_0x",
+      "hyperliquid_testnet": false,
+      "deepseek_key": "sk-xxxxxxxxxxxxx",
+      "initial_balance": 1000.0,
+      "scan_interval_minutes": 3
+    }
+  ],
+  "use_default_coins": true,
+  "api_server_port": 8080
+}
+```
+
+**Key Differences from Binance Config:**
+- Replace `binance_api_key` + `binance_secret_key` with `hyperliquid_private_key`
+- Add `"exchange": "hyperliquid"` field
+- Set `hyperliquid_testnet: false` for mainnet (or `true` for testnet)
+
+**⚠️ Security Warning**: Never share your private key! Use a dedicated wallet for trading, not your main wallet.
