This changes the execution order so that After(TestDiscovery) hooks run after dependencies are resolved but before ITestRegisteredEventReceiver and ITestDiscoveryEventReceiver are invoked. This allows hooks to set up state that event receivers can use during registration. Also reorders ITestDiscoveryEventReceiver to fire before ITestRegisteredEventReceiver for semantic clarity - discovery events should fire before registration events. New execution order: 1. Before(TestDiscovery) hooks 2. Test discovery & building 3. Dependency resolution 4. After(TestDiscovery) hooks (discovery phase complete) 5. ITestDiscoveryEventReceiver.OnTestDiscovered() 6. ITestRegisteredEventReceiver.OnTestRegistered() (registration phase)
