Skip GPN test and catalog reclassification when device is already classified. IdleState skips GPN if gpnStatus=supported AND parameters exist. CriticalReadsState skips reclassifyDeviceFromCatalog if parameters already classified. Avoids unnecessary RPCs on subsequent sessions. All 809 tests pass. Build status: Success
