• Exchange job constraints: Buy and burn GOLDAO if the ratio is 1:500 GOLDAO or higher. Buy and stake OGY as long as the ratio is 1:1000 OGY or higher (current is 1:3000). If neither of the above conditions is met, increase the ICP neuron and compound the interest.
• Neuron Staking deature: Added the ClaimOrRefresh call to the governance canister after funds transfer (both NNS and SNS support)

Fixed
