Supports HAMi #2034 (mode-agnostic Ascend scheduling).
Problem: The device plugin only applies soft slicing when a pod sets huawei.com/vnpu-mode: hami-core. Pods
without the annotation always take the legacy vNPU path, so on hami-core-only nodes they stay Pending.
Proposal: For annotation-less pods, resolve the mode from the node — use hami-core when the node reports
IsHamiVnpuCore(), otherwise the template path. Pods that pin a mode are unchanged.
