Remove -run filter that doesn't work with Ginkgo tests

- Ginkgo tests don't use Go's standard -run flag for filtering
- All tests are under TestE2ETestcases function, not separate Test functions
- Removed -run "Keyword Routing" from test execution
- Removed -run "Keyword Routing" from race detector
- Tests now run successfully and achieve 87.1% coverage of keyword_classifier.go
