fix: HostFactory 參數封裝外部化、SonarCloud 程式碼品質修復、靜態方法優化

1. HostFactory 參數封裝外部化
   - HostFactory.cs：CreateHost 方法簽章簡化，改為接收單一 HostConfigBundle 參數（原本在方法內部建立）
   - HostFactory.cs：HostConfigBundle record 從 private 改為 internal，允許外部建立
   - Program.cs：在呼叫 HostFactory.CreateHost 前建立 HostConfigBundle 實例，提升配置組合的靈活性

2. SonarCloud 程式碼品質修復
   - ExtensionManager.cs：processCleanupManager?.Dispose() 加入 #pragma warning disable/restore S2589 抑制「Boolean expressions should not be gratuitous」警告（條件式 Dispose 為防禦性程式碼）

3. 靜態方法優化
   - ExtensionSessionBridge.cs：CreateMetadata 方法改為 static（不使用實例成員，符合 CA1822 建議）
