Research direction

Start with the attached GitHub.vscode-codeql-unresponsive.cpuprofile.txt profile and the linked VS Code guidance on explaining extension CPU load. Compare the profile with the reported vscode-codeql 1.3.3, VS Code 1.49.2, and Windows environment. Done means identifying the extension activity responsible for the high CPU load and verifying that it no longer causes the reported performance problem.
