Merge branch 'dev' into fix-manifest-cache-invalidation

OverlayImpl::getManifestsMessage() caches manifest messages and only rebuilds
them when ManifestCache::sequence() changes. When accepting a new manifest,
the function returned early without incrementing seq_, causing the cache to
never invalidate. This meant peers were exchanging stale lists.

Now seq_++ is called for both new manifests and updates, ensuring the overlay
layer detects changes and sends complete validator lists to connecting peers.

Closes #629
