What it does

For each domain, this actor connects via TLS and extracts complete certificate details including issuer, expiration, certificate chain, SANs, and negotiated protocol. Use it for:

Certificate expiry monitoring — find certificates expiring in the next 30/60/90 days
Security audits — verify certificate chains, signature algorithms, and TLS versions
Compliance checks — ensure all domains use current TLS standards
Domain portfolio management — bulk-check hundreds of domains at once
Vendor risk assessment — verify SSL health of third-party services

`domains`	Array of strings	Domains to check (e.g., `google.com`, `github.com`)
