Queries this service's own DNS server for every intercepted
Bose hostname (api.bose.com, content.api.bose.io, etc.) and
verifies the answer is the configured service IP. Catches:
- DNS subsystem disabled or unbound (speakers using us as
their resolver get NXDOMAIN).
- DNS running but answers point at a stale IP (operator
changed the LAN address without restarting).
- Subset of intercepts silently failing — emits the failing
hostname list explicitly so it's obvious which patterns are
falling through shouldIntercept.
For the mismatch case the finding includes a copyable
`nslookup … <our-dns-bind>` so operators can verify the same
behaviour from the speaker's network.
To avoid duplicating the intercept list, exports it as
`discovery.InterceptedBoseHosts` instead — same string slice
that DNSDiscovery.shouldIntercept walks.
