Ensure `hookManager.StartAll()` is called + +### Events Not Triggering + +**Problem**: Hook is active but events aren't reaching the AI + +**Solutions**: +1.

Limit the number of active hooks + +### Memory Leaks + +**Problem**: Memory usage grows over time + +**Solutions**: +1. Ensure `Dispose()` is called when hook stops +2.
