DBX SSH plugin 0.7.5-beta.2

预发布(Pre-release)——基于 0.7.4 的三个 bug 修复,manifest 与 0.7.4 完全同构。beta.1 因误带 0.7.5 的调度任务功能(task-provider)在部分宿主上安装失败,请以本版为准。

• SFTP 大目录滚动修复(#151):文件较多时滚动失效、列表展示不全——虚拟滚动 spacer 与行列表被 v-else 写成互斥,滚过前几行后行列表整体消失。现二者并存,滚到底最后一个文件可见;附 2000 行 mock 夹具与结构守卫用例。
  SFTP large-directory scrolling fix (#151). With many files, wheel scrolling died and the list was cut off — the virtual-scroll spacer and the row list were wrongly paired with v-else. They now coexist; the last file is reachable.
• 弹窗窄视口溢出修复(#153):窄窗口下弹窗右半偏出屏幕(最宽的审计日志 680px 最先暴露)。定位器补 minmax(0,1fr) 网格轨道,所有弹窗窄视口正确收缩居中,宽视口不变。
  Narrow-viewport dialog overflow fix (#153). On narrow windows dialogs had their right half off-screen (the 680px Audit log first). The positioner now pins minmax(0,1fr) tracks; all dialogs shrink and stay centered.
• 文本预览选区色加深(#155):选取高亮与背景几乎无法区分(对比度 ~1.2:1)。明暗两套选区色加深提透明度,选中范围清晰可辨。
  Text-preview selection color deepened (#155). The selection highlight was nearly indistinguishable (~1.2:1 contrast); both themes are deepened for clear selections.
