doesn't matter. could disable all of them

Additional context

No response

Reproduce in a root-run custom devcontainer with VS Code 1.100.2 and C/C++ Extension 1.26.1, then inspect extension activation around dist/src/main.js and the failed extension.pickNativeProcess registration shown in the log. Done means the extension activates in that environment and goto definition works without the duplicate-command error; no repository test is named in the report.
