- feat(terminal): configurable default shell with backend-driven picker — `get_available_terminal_shells` / `probe_terminal_shell_path` serve the platform-aware option list, install state and `resolve_shell()` fallback; the settings UI renders the response verbatim and supports a custom shell path on every platform. POSIX spawn now distinguishes bash-family shells from unknown shells like nu/xonsh/elvish so the latter spawn cleanly without bash-only `-l -i` / `eval` flags. Localized across all 10 languages. Thanks to @Kwensiu for contributing the initial implementation in #127.
- feat(chat): file paths in Read/Write tool call headers and Edit/ApplyPatch diff headers are now clickable and open the file in the workspace panel via the existing local-file confirmation dialog; new-file Write/NotebookEdit bodies render with the same green tint as added diff lines.
- feat(chat): cap inline code block height inside messages with internal overflow scroll, so long code dumps no longer push the rest of the conversation off-screen.
- fix(dialog): constrain `DialogContent` to viewport height with internal scrolling, and cap the git reset commit message at 8rem with its own scrollbar, so the dialog footer stays visible on long messages or short viewports.

# 发布版本 0.11.1

- 新增(终端)：默认 Shell 改由后端驱动选择 —— `get_available_terminal_shells` / `probe_terminal_shell_path` 提供与平台相关的可选项、安装状态及 `resolve_shell()` 兜底逻辑，设置界面按后端返回原样渲染；所有平台均支持自定义 Shell 路径输入。POSIX 层在 spawn 时区分 bash 家族 Shell 与 nu/xonsh/elvish 等非 bash Shell，避免后者因 `-l -i` / `eval` 等 bash 专属参数无法启动；新增字符串已覆盖全部 10 种语言。感谢 @Kwensiu 在 #127 中贡献初版实现。
- 新增(聊天)：Read/Write 工具调用头部以及 Edit/ApplyPatch 差异头部中的文件路径现已可点击，复用既有的本地文件确认弹窗在工作区面板中打开；新文件场景下 Write/NotebookEdit 正文使用与新增差异行一致的绿色高亮渲染；
- 新增(聊天)：消息中的行内代码块高度被限制并启用内部滚动，长代码片段不再把后续对话挤出可视区域；
- 修复(对话框)：`DialogContent` 限制到视口高度并启用内部滚动，Git 重置提交消息限高 8rem 带独立滚动条，长消息或小视口下底部按钮始终可见。
