v1.1.0

11 MCP tools over the hosted server at https://dnsdoctor.dev/mcp: full domain scans (SPF, DKIM, DMARC, MX, DNS, blacklist, domain/TLS expiry), DMARC enforcement upgrades, and seven focused checks — SPF lookup counting and validation, DMARC record validation and generation, DKIM selector checks, DMARC aggregate report parsing, live DNS record verification, and reverse DNS. start_monitoring_signup replaces enroll_monitoring_trial: the agent hands the domain owner a signup link instead of us sending email.
