Uptime / latency / cert snapshot API

Issues a GET and measures HTTP status, time to first byte, total time, downloaded body size, and redirect status, then for https URLs reads the TLS certificate's days-until-expiry — all in one call with health flags. The value-add: status + latency + payload size + redirect + cert expiry in a SINGLE normalized snapshot. Answers 'is this site up', 'how fast does this URL respond', 'what's the TTFB for this site', 'when does this site's SSL cert expire'.
