Pull request overview
This PR fixes a flaky activation test that was failing intermittently on Windows CI by replacing a hardcoded 4-second delay with a polling approach that checks for extension activation up to 30 seconds.
Changes:
- Replaced fixed
delay()calls with a newwaitForActivation()function that polls extension status - Implemented polling logic with 100ms intervals and 30-second timeout

Generally LGTM, but some of the CCR comments might be worth looking into.
The activation test was failing intermittently on Windows CI because it used a hardcoded 4-second delay after opening a .ql file to wait for the extension to activate. On slower machines, this wasn't enough time. Replace the fixed delay with a polling loop that checks ext.isActive every 100ms for up to 30 seconds. This ensures the test: - Returns quickly on fast machines - Doesn't fail prematurely on slow machines
