[Fix] (DirectVulkan): age-based eviction for the content-addressed cache family - ProgramFactory entries (shader modules/layouts), PipelineFactory graphics pipelines, compute pipelines and per-layout descriptor-set tracking now retire after ~1024 idle frame boundaries (render-pass-manager sweep precedent), render-pass eviction purges pipelines hashed on the dying handle (closes a handle-recycling stale-pipeline hazard), and the program reflection cache is lifetime-id-keyed and cleared at EGL teardown - shader/program churn no longer grows Vulkan objects without bound
