The input peer.kind from channel plugins was used as-is without
normalization via normalizeChatType(), while the binding side correctly
normalized. This caused "dm" !== "direct" mismatches in
matchesBindingScope, making plugins that use "dm" as peerKind fail to
match bindings configured with "direct".
Normalize both peer.kind and parentPeer.kind through normalizeChatType()
so that "dm" and "direct" are treated equivalently on both sides.
