feat(tui): 工具显示卡片 + /model 与 /effort 运行时切换#593
Merged
Conversation
把 agent_loop verbose 的 `🛠️ Tool` 块替换为紧凑卡片： - file_write/file_patch：带行号+上下文的主题化 diff（append/prepend 走整文件 diff） - file_read：读到的内容带行号 gutter，噪音剥离，超长折叠 - code_run：CC/Codex 式 gutter 卡（命令 │ / 输出 └），保尾截断 - 三卡共用 _CardWriter/_card_status_row/_emit_gutter；2 格 margin 不进复制 - capture：tool_before/after 钩子(live) + iter_write_captures(continue) 内容寻址 - 双流渲染对齐(_align_md_renders)支持 margin 映射，复制不含视觉缩进
- /model：在线拉模型列表的 searchable picker；搜索框兼作自定义模型名输入 (无匹配时 Enter 直设)。逻辑在 model_cmd.py（agent 无关、可单测）。 - /effort：reasoning effort 档位切换。各协议差异在 effort_note 单点编码： Claude(output_config.effort) low/med/high 原样、xhigh→max、none/minimal 忽略； OpenAI(reasoning_effort / reasoning.effort) 透传。mixin 经 _BROADCAST_ATTRS 广播到全部子渠道。 - model_cmd：_resolve/fetch_models/set_model/set_effort，mixin 落子 session。

The tool-cards change (#593) tightened _md_line_has_box_drawing to exempt pure-horizontal '─' runs as markdown hr. But a SIMPLE-box Markdown table's only box glyph is its header rule, so that exemption dropped whole tables out of the passthrough copy path and into the wide-render aligner, which maps selection cell-columns to character indices — misaligning copy of any table with CJK (wide) cells. Remove the pure-horizontal exemption so a table's header rule is detected again and the table run stays passthrough. Card gutters (└─ / │ / └) keep their own prefix-based exemptions, so tool cards are unaffected. The only cost is a real markdown hr copying as a dash run — the pre-#593 behavior.

tuiapp_v2 的两项增强，拆成两个 commit。 ## 1. 工具显示卡片（file_write / file_patch / file_read / code_run） 把 agent_loop verbose 的 `🛠️ Tool` 块替换为紧凑卡片： - **file_write / file_patch**：行号 + 上下文的主题化 diff；append/prepend 走整文件 diff 拿真实上下文。 - **file_read**：读到的内容带行号 gutter，剥离 LLM-facing 噪音（`[FILE]`/show_linenos 前言/截断提示），超长折叠；行号在不可知处（keyword 窗口 / 挖洞后）留空。 - **code_run**：参考 Claude Code / Codex 的 exec 渲染，无边框、`│` 命令 gutter + `└` 输出 gutter，输出 dim、**保尾截断**（traceback 关键在末尾）；代码来自正文 ```块``` 时不重复展示。 - 三卡共用 `_CardWriter` / `_card_status_row` / `_emit_gutter`；2 格左 margin 只进显示流、不进复制源。 - capture 机制：live 走 `tool_before/after` 钩子，`/continue` 走 `iter_write_captures` 从历史 tool_result 重建，按 `hash(get_pretty_json(args))` 内容寻址。 - 双流渲染对齐（`_align_md_renders`）支持 margin 映射，鼠标复制不含视觉缩进。 ## 2. /model 与 /effort 渠道内运行时切换 - **/model**：在线拉模型列表的 searchable picker；搜索框兼作自定义模型名输入（无匹配时 Enter 直设）。 - **/effort**：reasoning effort 档位切换，协议差异在 `effort_note` 单点编码——Claude(`output_config.effort`) low/med/high 原样、xhigh→max、none/minimal 忽略；OpenAI(`reasoning_effort` / `reasoning.effort`) 透传；mixin 经 `_BROADCAST_ATTRS` 广播到全部子渠道。 - 逻辑收在 `frontends/model_cmd.py`（agent 无关、可单测）。 ## 测试 - 卡片：两份真实会话日志全链路重放，51 个 code_run + 23 read + 20 write 全部渲染、双流 parity、复制不含 margin。 - /model /effort：拦截真实 llmcore 请求构造验证 effort 进 payload（含 mixin 广播、各协议字段）；picker 自定义输入走 Textual pilot 端到端。
