feat(exchange): add Bybit Futures support (#1100)
* feat(exchange): add Bybit Futures support - Add Bybit Go SDK dependency (github.com/bybit-exchange/bybit.go.api) - Create trader/bybit_trader.go implementing Trader interface for USDT perpetual futures - Update config/database.go to include Bybit in default exchanges - Update manager/trader_manager.go to handle Bybit API key configuration - Update trader/auto_trader.go to add BybitAPIKey/BybitSecretKey fields and bybit case - Add Bybit icon to frontend ExchangeIcons.tsx Bybit uses standard API Key/Secret Key authentication (similar to Binance). Only USDT perpetual futures (category=linear) are supported. Co-Authored-By: tinkle-community <tinklefund@gmail.com> * test(bybit): add comprehensive unit tests for Bybit trader - Add BybitTraderTestSuite following existing test patterns - Interface compliance test (Trader interface) - Symbol format validation tests - FormatQuantity tests with 3-decimal precision - API response parsing tests (success, error, permission denied) - Position side conversion tests (Buy->long, Sell->short) - Cache duration verification test - Mock server integration tests for API endpoints All 12 Bybit tests pass. Co-Authored-By: tinkle-community <tinklefund@gmail.com> * fix(frontend): add Bybit support to exchange config forms 修復前端對 Bybit 交易所的支持： - 添加 Bybit 到 API Key/Secret Key 輸入欄位顯示邏輯 - 添加 Bybit 的表單驗證邏輯 - 修復 ExchangeConfigModal.tsx 和 AITradersPage.tsx Co-Authored-By: tinkle-community <tinklefund@gmail.com> --------- Co-authored-by: the-dev-z <the-dev-z@users.noreply.github.com> Co-authored-by: tinkle-community <tinklefund@gmail.com>
