* fix(mdns): answer hostname A queries after TTL
Zeroconf answers only service queries. The A record for <alias>.local
expired from the OS cache after 120 seconds and lookups then failed.
Vendor zeroconf v1.0.0 with one change: it now answers A and AAAA
queries for the registered hostname. Fixes#95.
* fix(deps): update golang.org/x/net to v0.60.0
govulncheck reports several x/net advisories fixed in v0.60.0.
The Security Scan job fails on them.
