chore: import original project baseline

Import the pre-repair source tree as the history baseline.
Runtime data (data/), virtualenvs, bytecode caches and logs are
gitignored so local secrets and user state stay out of the repo.

+"""独立调试器窗口 —— 与主窗口/项目树完全解耦（顶层窗口，parent=None）
+
+功能:
+  Tab1「调试会话」  实时 tail data/debug_session.log，按来源着色:
+                   [USER]蓝 / [AGENT]绿 / [APP]灰 / [SYS]紫
+  Tab2「应用日志」  实时 tail diag.log + compaction_diag.log + stream_diag.log
+  底部输入框        用户输入观察到的情况，回车 → 记 [USER]
+  按钮              暂停显示 / 清空会话日志 / 打开日志文件
+
+控制: 代理写 data/debug_window.cmd (show/hide)，主窗口 2s 轮询后调用本窗口。
+本文件不 import main_window，可独立离屏测试。
