fix: avoid IndexError in BF16_Optimizer.destroy() when using DummyOptim (#7763) fix: avoid IndexError in BF16_Optimizer.destroy() when using DummyOptim Short-circuit BF16_Optimizer.destroy() if using_real_optimizer is False. When initialized with optimizer=None (DummyOptim), bf16_groups remains empty, causing an IndexError when accessing it in destroy(). Resolves #7752
