Multi Server Https

A plain HTTP primary server plus an HTTPS server on a second port. Each additional listener carries its own TLS context in the extra-listener table, so its accepts do their own SSL handshake while the primary stays plain — an app that serves plain HTTP on one port and HTTPS on another, in one process. Try the HTTPS port with: curl -k https://127.0.0.1:<port>/hello

{ cert, key } are PEM strings (a throwaway self-signed pair, inline so the example is self-contained). A self-closing sequence keeps it runnable to completion.
