feat(movement): send jump packet to server (opcode 0xF61B)

Browse source 
Build and send GameAction(Jump) with extent + world-space launch
velocity + sequence counters. Wire format from holtburger
JumpActionData::pack. Server can now validate and replicate jumps
to nearby clients.

Also compute RunRate locally via PlayerWeenie.InqRunRate when
running (server doesn't echo UpdateMotion ForwardSpeed to sender).
