fix: pass tool_call_timeout to shell.exec for configurable shell timeout

PR 描述（Draft）

Modifications / 改动点

修复了 astrbot_execute_shell 工具的超时时间配置功能，使得用户可以通过管理面板中的"工具调用超时时间（秒）"设置来控制 shell 执行的超时时间。

问题描述：

• 之前 ExecuteShellTool 调用 shell.exec() 时，没有传递 timeout 参数，导致始终使用接口默认的 30 秒超时
• 用户即使将 tool_call_timeout 设置为 600 秒，shell 执行仍然是 30 秒就超时

修复方案：

• 从 context.tool_call_timeout 获取配置的超时时间
• 将 tool_call_timeout 传递给 shell.exec() 的 timeout 参数

Screenshots or Test Results / 运行截图或测试结果

注意：这是一个 Draft PR，目前代码尚未经过实际测试。

测试步骤建议：

1. 在管理面板中设置 tool_call_timeout 为较大值（如 600）
2. 使用 astrbot_execute_shell 工具执行一个耗时较长的命令
3. 验证 shell 执行是否能在 30 秒后继续运行，直到达到配置的超时时间

Summary by Sourcery

Bug Fixes:

• Ensure astrbot_execute_shell uses the context-provided tool_call_timeout value when invoking shell.exec so long-running commands respect the configured timeout.

Code Review

This pull request updates the shell tool to incorporate a configurable timeout for command execution by passing context.tool_call_timeout to the sb.shell.exec method. The review feedback suggests simplifying the implementation by removing the intermediate variable and the Chinese comment to improve code clarity and maintain style consistency.

[gemini-code-assist]

建议移除冗余的中间变量和中文注释，直接将 context.tool_call_timeout 传递给 sb.shell.exec。根据 Google Python 风格指南，代码注释应使用英文以保持一致性，且此处代码逻辑已足够清晰，无需额外注释。

            result = await sb.shell.exec(
                command, background=background, env=env, timeout=context.tool_call_timeout
            )
