fix(python): exclude virtual environments from detected roots whatever their name

Root detection only skipped environments named `venv` / `.venv`. A venv with another name in the project (e.g. `code10`) was walked into, and any package in its site-packages that ships `pyproject.toml`, `setup.py` or `requirements.txt` became a source root. Source roots go on PYTHONPATH for runs, so a package directory with an `io` package shadowed the standard library and Python 3.10 failed at startup with `init_sys_streams: module 'io' has no attribute 'open'`. A directory with `pyvenv.cfg` (venv, virtualenv, uv) or `conda-meta` (conda) is now an excluded root and not searched for modules; creating one re-runs detection. Project discovery in the workspace folder picker skips such directories too, so packages inside an environment are not offered as projects.

 Notes on what they do:
@@ -96,28 +94,16 @@ Notes on what they do:
 - `read_file` also reads sources of dependencies and files inside jar and zip archives.
 - `search_symbol` and `find_references` use the IDE's index and the language servers; `get_symbol_info` returns what Quick Documentation shows.
 - `get_file_problems` and `get_project_problems` return what the Problems tool window shows, after your inspection profile is applied, rather than a fresh analysis.
- `check_files` is the fresh analysis, for after an edit made by any tool: it syncs each file from disk, tells its language servers it was saved (so on-save checks such as `cargo check` run) and waits until they answered and finished. Each file gets a `status` that says whether the problems are complete, or why it could not be checked: no language server for it, or one that is not installed, misconfigured or crashed.
 - `rename_refactoring` renames through the language server, so references that a text search would miss are updated too. It can preview without writing.
 - `apply_patch` accepts the Codex `apply_patch` format and unified diffs. Paths must stay inside the project.
 - `git_diff` compares files on disk, so unsaved editor text is not included.

-## Commands in the Run tool window
-
-`run_command` runs a shell command line in a tab of the Run tool window, with the shell of **Settings › Tools › Terminal**. The agent names the tab and OpenIDEA shows it as `_agent_<name>`, so you see the output as it comes and can type into the command, rerun it or stop it like any run.
-
-As JetBrains IDEs do, the command runs on pipes, not a terminal: programs print plain lines instead of progress bars and redraws. The agent gets that output cleaned of escape sequences and cut to 2000 lines (`maxLinesCount`); beyond that the end stays, or the start or both ends with `truncateMode`. The tab's raw output log stays complete.
-
- **One tab per name.** A name whose command finished runs the next command in the same tab. A name whose command is still running is refused, with that command and its last output: the agent has to stop it with `stop_run` first or pick another name. Nothing is stopped behind your back.
- **Following a command up.** `wait_for_run` waits for the command to end or for a pattern in its output (a server's "listening" line), `read_run_output` reads the output from any point, `get_run_status` tells whether it is running, succeeded, failed, crashed or was stopped by the agent or by you, and `send_run_input` writes text and Enter to its input; Ctrl+C stops it and Ctrl+D ends its input.
- **You can step in.** What you type into the tab's input line, a rerun, a Stop and closing the tab are reported to the agent with their time. A wait ends at once, and the agent is advised to stop what it is doing, tell you it received the intervention and wait for your confirmation.
- **Finished tabs are greyed out.** Beyond **Finished agent tabs to show** (1 by default) the oldest finished ones move to an archive at the end of the tab strip, shown as **Archived (n)**. Beyond **Archived agent tabs to keep** (999) the oldest archived ones are closed. Running commands are never archived or closed. Both settings are on **Settings › Agents › IDE MCP Server**.
-
 Plugins can add more tools; they appear in the same list. A plugin tool marked as destructive asks for confirmation the same way.

 ## Safety

 - **Untrusted projects** expose only the read-only tools. Tools that write files, rename, reformat, build or run need a project you have trusted.
- **Running and building ask first.** `execute_run_configuration`, `build_project` and `run_command` show a dialog in OpenIDEA naming the client, the project, the tool and what will run. Choose **Allow** or **Deny**; several requests queue up.

 几点说明：
@@ -95,28 +93,16 @@ stdio 配置大致如下（路径以你机器上的为准）：
 - `read_file` 还能读取依赖的源代码，以及 jar 和 zip 压缩包中的文件。
 - `search_symbol` 和 `find_references` 使用 IDE 的索引和语言服务器；`get_symbol_info` 返回的内容与快速文档相同。
 - `get_file_problems` 和 `get_project_problems` 返回的是问题工具窗口当前显示的内容（已应用你的检查配置文件），而不是重新分析的结果。
- `check_files` 才是重新分析，适合在任何工具修改文件之后调用：它从磁盘同步每个文件，通知语言服务器文件已保存（这样 `cargo check` 等保存时检查也会运行），并等到服务器答复且分析完成。每个文件都有一个 `status`，说明问题列表是否完整，或者为什么无法检查：没有对应的语言服务器，或者服务器未安装、配置错误、已崩溃。
 - `rename_refactoring` 通过语言服务器重命名，文本搜索找不到的引用也会一并更新；也可以只预览不写入。
 - `apply_patch` 接受 Codex 的 `apply_patch` 格式和 unified diff，路径必须在项目内。
 - `git_diff` 比较的是磁盘上的文件，不包含编辑器中尚未保存的内容。

-## 在运行工具窗口中执行命令
-
-`run_command` 在运行工具窗口的一个标签页中，用 **设置 › 工具 › 终端** 中配置的 shell 执行一条命令行。标签名由智能体指定，OpenIDEA 显示为 `_agent_<名称>`。输出实时可见，你也可以像对待其他运行一样向命令输入、重新运行或停止它。
-
-和 JetBrains 的 IDE 一样，命令通过管道运行，而不是在终端里运行：程序输出的是普通文本行，不会有进度条和屏幕重绘。智能体拿到的输出会去掉控制字符，并截断到 2000 行（`maxLinesCount`）；超出部分默认保留结尾，也可以用 `truncateMode` 改为保留开头或两头。标签页的原始输出日志保持完整。
-
- **一个名称对应一个标签。** 名称对应的命令已结束时，下一条命令在同一标签中运行。命令仍在运行时会被拒绝，并返回该命令和它最后的输出：智能体必须先用 `stop_run` 停止它，或者换一个名称。任何进程都不会被悄悄停掉。
- **跟进命令。** `wait_for_run` 等待命令结束，或等待输出中出现指定文本（例如服务器的“正在监听”一行）；`read_run_output` 从任意位置读取输出；`get_run_status` 报告命令是在运行、成功、失败、崩溃，还是被智能体或你停止；`send_run_input` 向命令的输入写入文本和 Enter，Ctrl+C 会停止命令，Ctrl+D 结束它的输入。
- **你可以随时干预。** 你在标签输入行中输入的内容、重新运行、停止和关闭标签，都会连同时间一起告诉智能体。正在进行的等待会立即返回，并建议智能体停下手头的工作，回复你已收到干预，等你确认后再继续。
- **已结束的标签会置灰。** 已结束的标签超过 **显示的已结束智能体标签数**（默认 1）时，最旧的会移入标签栏末尾的归档，显示为 **归档(n)**。归档超过 **保留的已归档智能体标签数**（默认 999）时，最旧的会被关闭。正在运行的命令永远不会被归档或关闭。这两项设置位于 **设置 › 智能体 › IDE MCP 服务器**。
-
 插件可以添加更多工具，它们会出现在同一个列表中。标记为破坏性操作的插件工具同样会先请求确认。

 ## 安全

 - **未受信任的项目** 只开放只读工具。写文件、重命名、重新格式化、构建或运行的工具都要求项目已被信任。
- **运行和构建会先询问。** `execute_run_configuration`、`build_project` 和 `run_command` 会在 OpenIDEA 中弹出对话框，说明是哪个客户端、哪个项目、哪个工具以及要运行什么，选择 **允许** 或 **拒绝**；多个请求会排队。
