Research direction

Start by reproducing the slowdown with Ubuntu 24.04 on WSL 2 using the reported Windows, WSL, and kernel versions, then compare it with Ubuntu 22.04. The report includes no diagnostic logs, source files, or tests; progress would require identifying the cause and verifying that Windows and Ubuntu return to expected responsiveness.
