主要改进

• 预览面板文字选择与放大镜工具栏：预览画布新增文字拖选高亮（光标变 I-beam，拖选自动归整到 glyph 边界，复用 GTK 文本复制流程），并在画布浮层基于浮点字形框精修消除与文字的错位；工具栏新增放大镜开关（Gtk.Fixed 定位修复画布 margin 溢出，画布侧支持打开后跟随真实 PDF、编译期间保持显示上一次编译结果）。预览渲染管线同步引入 draft 低分辨率兜底：单个耗时 > 200 ms 或有更高优先级构建在飞时自动降级到 draft，单帧端到端耗时 ~1650 ms → ~120 ms。

• 多光标编辑转正与列选拖动体验收紧：多光标编辑从实验性开关移除，改用分级门控（列选拖动阈值收紧、补齐 drag-end 抖动点击兜底，回归测试覆盖取消/拖出窗口/未触发修饰键三条边界），并修复多光标模式下的快捷键与交互残留问题。

• AI 设置整合与「在终端中打开 Agent」快速入口：AI 相关设置从独立页迁移到 General 页并更名为 AI Settings（含重排各页设置分组顺序、修复重置取消路径 NameError、阻止 ComboRow 重建冲掉用户保存的 active agent tool）。主窗口标题栏新增「在终端中打开 Agent」快速入口（裸启动 AI Fix 配置的 Agent CLI，不预填 prompt，工作目录 = 活动 LaTeX 文档所在目录），welcome 模式下隐藏避免空文档误操作。

• Git 集成：行级 diff 标记与侧栏面板（cvfosammmm#216 cvfosammmm#443）：编辑器 gutter 实时显示当前文件的增删行标记，Git 侧栏面板提供仓库状态浏览，配合已有的提交流程形成完整回路；偏好页 Git 面板 subtitle 裸 & 改为 Pango 实体 &，翻译文件同步更新（git 信任对话框 msgstr 结尾换行对齐）。

• 标签页 / 工作区关闭协议回归与编辑器稳定性收尾：关闭协议增加视图成员检测与 TabView page_belongs_to_this_view 契约修复，幽灵标签页与 Adwaita-CRITICAL 警告消除；未保存标签页的 Cancel/Esc 不会再误关；标题栏预览按钮跟随面板真实状态；旧 worker 被新构建取代后不再继续执行残留任务；搜索 Replace 按钮判定统一由 _current_match 提供并适配 GtkSource SearchContext 四元组返回值；预览期间避免文字选择高亮与文字错位。

Improvements

• feat: Preview canvas gains native text selection (I-beam cursor, drag-to-select snapped to glyph rectangles, GTK copy on highlight) and the canvas overlay is repositioned via Gtk.Fixed to stop margin overflow. The preview toolbar now has a magnifier toggle; the canvas keeps showing the previous build while a new compile is running. The render pipeline adds a draft low-resolution fallback — frames slower than 200 ms or with a higher-priority build in flight automatically downgrade to draft, taking end-to-end per-frame from ~1650 ms down to ~120 ms.

• feat/refactor: Multi-cursor editing is promoted out of the experimental gate into a tiered-gating default. The column-select drag threshold is tightened, a drag-end jitter-click fallback is added, and regression coverage now includes cancel / drag-out-of-window / missing-modifier edge cases. Latent shortcut and interaction glitches in multi-cursor mode are fixed.

• feat/refactor/fix: AI settings move from a dedicated page into General under the new name "AI Settings"; preference group order is rebalanced across all pages, the reset-cancel NameError is fixed, and ComboRow rebuilds no longer wipe the user's saved active agent tool. A new "Open AI agent in terminal" entry appears in the main headerbar (bare-launch of the AI-Fix-configured agent CLI with no pre-filled prompt, working directory = active LaTeX document), and is hidden on the welcome page so an empty document can't trigger it.

• feat/fix/i18n: Git integration adds per-line diff markers in the editor gutter and a sidebar repository panel, completing the loop with the existing commit flow alongside cvfosammmm#216 / cvfosammmm#443. The Git preferences panel's subtitle now escapes a bare & as Pango entity &; the trust-dialog msgstr trailing newlines are aligned, and translation files are refreshed.

• fix: The tab-close protocol grows view-membership detection plus the page_belongs_to_this_view TabView contract fix, killing ghost tabs and the Adwaita-CRITICAL warnings. Cancel/Esc on unsaved tabs no longer accidentally dismisses them; the headerbar preview button now follows the panel's real state; superseded build workers stop running leftover tasks. The search Replace button is sourced from _current_match and adapted to GtkSource's 4-tuple SearchContext return; text-selection overlays in the preview no longer drift off the glyphs.
