refactor: remove benchmarking debug code from CRITICAL-003

- Remove BENCHMARKING_MODE flag and detectionTimes list
- Remove printBenchmarkStats() and resetBenchmarkStats() functions
- Remove detailed benchmark logging from detection method
- Keep only essential timing log for normal operation
- Clean production code after performance testing complete
