Code Review

This pull request introduces a GlobalInputManager to centralize global input event handling and resolve focus issues related to double-tap shortcuts and drag-and-drop operations. Key changes include refactoring DoubleTapManager to use the new manager and implementing logic in WindowManager to delay window hiding during external drag events. A review comment identified a logical redundancy in the mouse-up event handler where visibility resolution was being triggered twice; it is recommended to refactor this into a single conditional branch to improve clarity and avoid duplicate execution.

这里存在逻辑冗余。hideAfterDeferredMouseUpIfNeeded 内部已经包含了对 resolveMouseUpVisibility 的调用。当 pendingBlurHideOnMouseUp 为 true 时，会导致 resolveMouseUpVisibility 被连续执行两次。建议根据 pendingBlurHideOnMouseUp 的状态进行分支处理，以提高代码清晰度并避免重复逻辑执行。

      if (this.pendingBlurHideOnMouseUp) {
        this.hideAfterDeferredMouseUpIfNeeded()
      } else {
        this.resolveMouseUpVisibility()
      }
