Connect-UDP-Bind client session for h2 / h3 (draft-ietf-masque-connect-udp-listen-11). Sibling of masque_client_session / masque_ip_client_session; one module serves both transports by dispatching on a transport field.

Public API surfaced via masque:

• masque:bind_connect/3 opens the tunnel.
• masque:send_to/3 sends a UDP payload to a peer.
• masque:assign_compression/2, masque:open_uncompressed_context/1, masque:close_compression/2 drive the compression-table lifecycle.
• masque:proxy_public_address/1 reads the parsed Proxy-Public-Address list.

Owner messages (sent to the owner pid passed in opts):

• {masque_bind_packet, Sess, {IP, Port}, UdpPayload}
• {masque_compression_assigned, Sess, ContextId, Peer}
• {masque_compression_acked, Sess, ContextId}
• {masque_compression_closed, Sess, ContextId}
• {masque_closed, Sess, Reason}
