Sprint (Tenacity 5.1, Sigma 3.9, Flux B39.11, Gugustus, Jigsaw 0.26, November 0.2, Raze Recode 2.0, Koks v1, Helium B41420)

START/STOP_SPRINTING for keep-sprint and WTap. START/STOP_SNEAKING for scaffold silent sneak. KeepSprint cancels incoming STOP_SPRINTING. Flight sends START_FALL_FLYING for elytra exploit. Disabler cancels all C0B packets.

// KeepSprint — cancel server STOP_SPRINTING
