one process swallow mDNS replies meant for another. On macOS it sets **both**
`SO_REUSEADDR` and `SO_REUSEPORT`, because the system `mDNSResponder` already
holds the port and a bare `SO_REUSEADDR` bind races with it.

Shared code lives in the local `shared/` Go module (imported as `nvpair-shared/…`, replaced via `replace nvpair-shared => ../shared`). It provides logging, wire types, JSON-RPC and IPC, discovery records, mDNS, network monitoring, stable node identity, application data paths, and cluster trust helpers.

The mDNS responder is our own rather than the host's, because Windows ships none. It sets `SO_REUSEADDR` so it shares UDP 5353 with sibling PAIR processes and with a system responder — `avahi-daemon` on Linux, Bonjour where present — needing no configuration on either platform.
