Fix hash_size using first-seen-wins instead of last-seen-wins

Browse Source 
The hashSizeMap was guarded by !hashSizeMap.has(pk), meaning the oldest
ADVERT determined a node's hash_size permanently. If a node upgraded
firmware from 1-byte to 2-byte hash prefix, the stale value persisted.

Remove the guard so newer packets overwrite older ones (last-seen-wins).
