Solana mainnet now enforces all Poseidon syscall inputs to be exactly 32 bytes. Left-pad sub-32-byte inputs inside Poseidon::hashv() right before the syscall/library call. This preserves field element values (leading BE zeros are a no-op) and keeps AsByteVec and #[truncate] backwards compatible. Bumps light-hasher 1.1.0 -> 1.1.1, light-sdk 0.11.0 -> 0.11.1.
