Vaulting over obstacles cancels vanilla sprint due to horizontal block collision in the first couple ticks of the vault animation. Since FastRun.canContinue() requires player.isSprinting(), this caused fast run to stop mid-vault, leaving the player walking after the vault completes.

The fix registers a sprint cancel marker in Vault.onStartInLocalClient so that the LivingEntityMixin setSprinting hook blocks vanilla's cancellation for the duration of the vault. This is the same pattern already used by RideZipline.

When vaulting, vanilla Minecraft cancels the sprint state due to the
horizontal block collision in the first 1-2 ticks of the vault
animation. This causes FastRun.canContinue() to fail (it requires
player.isSprinting()), stopping the fast run mid-vault.

Register a sprint cancel marker in Vault.onStartInLocalClient so that
the LivingEntityMixin setSprinting hook blocks vanilla's cancellation
for the duration of the vault (marker remains while isDoing() is true).
This follows the same pattern already used by RideZipline.
