Add -tbaud switch: force COM1 RIO baud for high-speed replica boards

-tbaud <rate> (9600-921600) overrides the COM1 baud rate while keeping
old-RIO (type 0) protocol behavior unchanged; independent of -trio.
SetupComm buffers 2/2 -> 1024/1024 only when the override is active.
Rebuilt Release + Profile (0 errors), deployed rel.bin\MW4.exe to MW4\.
run-firestorm driver: game-start now takes optional extra args.
CLAUDE.md: branch notes incl. the CP949 comment-encoding hazard
(mw4 sources must be edited byte-safely).
