- Migration v2: INSERT → INSERT OR IGNORE for idempotency
- Config: validate server.tls_cert and server.tls_key are non-empty
- gRPC: add input validation matching REST handlers
- gRPC: add logger to zone/record services, log timestamp parse errors
- REST+gRPC: extract SOA defaults into shared db.ApplySOADefaults()
- DNS: simplify SOA query condition (remove dead code from precedence bug)
- Startup: consolidate shutdown into shutdownAll(), clean up gRPC listener
on error path, shut down sibling servers when one fails

Populates the database on first run with the two existing zones
(svc.mcp.metacircular.net, mcp.metacircular.net) and all their A
records (metacrypt, mcr, sgard, mcp-agent, rift, ns).

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
