Prepare an unsigned transaction for SUI staking operations.
Transaction Types:
- delegate: Stake SUI tokens to earn rewards from Stakefish validator
- undelegate: Unstake SUI tokens and stop earning rewards
Important Notes:
- Delegation requires specifying the amount of SUI to stake
- Undelegation requires the stake object ID from previous delegation
- There is no unbonding period - undelegated SUI is immediately available
- Gas fees are paid in SUI from the sender's address
- Staking rewards are automatically compounded (no separate claim needed)
