IRewardVaultTokenProbe
Minimal probe interface for reading the active reward token from a
Berachain RewardVault. Neither the legacy nor vnext upstream interface
declares this view, but both concrete contracts expose it (legacy ABI
IERC20 public rewardToken; vnext function rewardToken() returns (IERC20)). Used to discriminate the BGT-paying vs WBERA-paying path
in the unified harvest view.
