- SocketConnection.processMessage() did 'new events[0].parserClass()'
where parserClass is typed as 'Function' on IMessageEvent (no
construct signature). Cast to 'new () => IMessageParser' at the
call site so the spawned instance is type-correct downstream.
- RoomChatHandler dispatched RoomSessionChatEvent with the args in
the wrong order: '[]' (intended as the 'links' array) was landing
in the 'chatColours' string slot. Swap to '"", []' so links go
to position 8 and chatColours stays a string.
