- Register -v/-q short flag aliases sharing the same bool variable as
--verbose/--quiet so both forms work identically
- Register -d and -dd flags; use ParseDebugLevel() helper so -d sets
Debug=1 and -dd sets Debug=2; remove the broken strings.Count approach
- Add AllowTCP field to dns.QueryConfig; guard TCP truncation fallback in
QueryWithExchange and IterativeQueryWithExchange behind cfg.AllowTCP;
wire cfg.AllowTCP from CLI config into QueryConfig in main.go
- ParseRootServer() now returns ErrInvalidRootServer instead of (nil,nil)
when the string is non-empty but net.ParseIP fails
- Add internal/config/config_test.go covering ParseQueryType, ParseUDPSize,
Validate, GetDomain, ParseRootServer, ParseDebugLevel, and the
--always-tcp/--allow-tcp cross-check
- Add TestQueryNoTCPFallbackWhenDisabled to dns/query_test.go
- Update existing truncation tests to set AllowTCP:true
- Add TODO comments on display flags not yet wired to output layer
