feat(desktop): 插件设置页添加隐藏 claude-mem observer 会话的开关

[963656544]

Summary

在 claude-mem 插件详情页新增"隐藏 observer 会话标签页"开关，开启后侧边栏自动过滤
claude-mem 后台观察线程产生的会话记录。

claude-mem 通过 Claude Agent SDK 在后台启动 observer session 监控主会话并生成进度摘要，
这些会话的 session 文件被 cc-haha 扫描到后展示在侧边栏中，用户看到不属于自己操作的内容，
容易造成困惑。

Test plan

• 安装 claude-mem 插件后，进入 设置 → 插件 → claude-mem，能看到"隐藏 observer 会话标签页"开关
• 开关默认关闭，侧边栏正常显示所有会话
• 开启开关后，侧边栏中 claude-mem observer 项目下的会话立即消失
• 关闭开关后，observer 会话恢复正常显示

Hi @963656544! I'm Dosu and I’m helping the cc-haha team.

I don't perform code reviews (assessing PRs for bugs, design, style, performance, or security). However, I can help in other ways:

• Research the affected code — I can look into how session filtering or plugin settings are currently implemented in the codebase.
• Answer questions — e.g., how the sidebar populates sessions, how claude-mem observer sessions are identified, etc.
• Suggest documentation updates — if this feature needs docs or changelog entries.

Let me know if any of those would be useful!

To reply, just mention @dosu.
