Introduces an `AddressType::Lan` slot that stores a peer's private, link-local, or loopback path alongside its existing relay/direct/ unverified/NATted entries. Same-LAN peers can now retain a fast local path without evicting their WAN path, capped at one extra slot per IP family. Address publication, gossip merges, find-node responses, and dial selection all filter LAN-tagged entries down to receivers we believe share our LAN/WAN, drop relay candidates that resolve to our own observed WAN IP, and rewrite our own LAN IP to loopback for the receiver where appropriate.

Summary
AddressType::Lanas a new highest-priority address slot so same-LAN peers retain a fast local path alongside their relay/direct/unverified/NATted entries (one extra slot per IP family, capped at 3).Test plan
