Replace the CoreDNS precursor with a purpose-built authoritative DNS server. Zones and records (A, AAAA, CNAME) are stored in SQLite and managed via synchronized gRPC + REST APIs authenticated through MCIAS. Non-authoritative queries are forwarded to upstream resolvers with in-memory caching. Key components: - DNS server (miekg/dns) with authoritative zone handling and forwarding - gRPC + REST management APIs with MCIAS auth (mcdsl integration) - SQLite storage with CNAME exclusivity enforcement and auto SOA serials - 30 tests covering database CRUD, DNS resolution, and caching Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
