release(v2.1.2): Linux mDNS local-discovery

Adds the CHANGELOG entry for this pass's mDNS work (local_discovery.go, hosts_override.go -- see prior commit for the two real bugs found via live testing), bumps AgentVersion, and documents prefer_local_directory in agent.yml.example. Also backfills CHANGELOG entries for v2.1.0/v2.1.1 (Windows agent, WireGuard client, installer, CI), which were tagged and released but never documented here.
