Detect new or changed SSL certificates

Monitors hosts for certificate changes between runs. The first run outputs everything with the full chain; later scheduled runs only return domains whose certificate fingerprint changed (renewal, new issuer, replacement). Supports custom ports. Useful as a security audit trail.
