[MoE] Failed to initialize router:

Error message

[MoE] Failed to initialize router:

What it means

Log warning from getMoERouter's singleton setup: the background initialization of the MoE router (which loads persisted weights) failed, so the router runs untrained/default while still being returned to callers.
