pub const COMMCONFIG_PRE_LOGIN_TIMEOUT: Duration;Expand description
C++ login waits up to 30 seconds for pre-login CommonConfig and allows login to continue when that request cannot be replayed.
Ref: FutuOpenD/Src/FTGateway/FTGateway.cpp:288-291 passes 30000 with
bIgnoreWhenUnReplay=true, and :798-799 makes pull failure non-fatal.
This fixed value is protocol-parity evidence, not server configuration;
revise it if the upstream pre-login wait contract changes.
