- Fix move constructor and move assignment: set other.ownsSampler_ to false after transfer (was incorrectly set to true, leaving moved-from object claiming ownership of a null sampler) - Fix destroy(): reset ownsSampler_ to false after clearing sampler handle (was set to true, inconsistent with null handle state) - Extract finalizeSampler() from 3 duplicated cache-or-create blocks in createSampler() overloads and createShadowSampler() (-24 lines) - Add SPIR-V alignment why-comment in vk_shader.cpp
