Prod do_matching captures (data_dumps/captures/traffic_prod_tk2_*) send
the node URL as host:port/socket.io/ with no scheme prefix —
e.g. "node06.shadowverse.jp:13560/socket.io/". BestHTTP's SocketManager
expects this exact shape; the leading ws:// we were sending plus the
missing /socket.io/ path was preventing the client from completing the
post-do_matching connect (eventually times out with "connection timed
out").
Update BattleNodeOptions default, Program.cs override, and both
controller and bridge tests to use "localhost:5148/socket.io/".
Discovered during v1 smoke walkthrough.
