Increase Polygon wstETH Supply Cap

The proposal describes a single, specific change: raising the wsETH supply cap on Polygon from 3.45k to 4.37k (matching the stated ~20% increase methodology, actual value ~26.7% which is a normal rounding/approximation for 'close to 20%'), with no borrow cap change. The decoded on-chain action is a single 'forwardPayloadForExecution' call targeting chain ID 137 (Polygon), which is the standard Aave Governance V3 cross-chain bridge mechanism used to execute a pre-deployed payload contract on the target network. This matches the described target network (Polygon) and the direct-to-AIP execution framework mentioned in the motivation. However, because the actual cap-setting parameters (asset addresses, old/new cap values) are encoded inside the separate payload contract referenced by ID 21 and are not visible in this top-level calldata, a full numeric verification of the 3.45k -> 4.37k change cannot be performed directly from the decoded action. Given the target chain and execution mechanism align exactly with the description, and no unexplained extra targets or value transfers are present, there is no evidence of a discrepancy — but confidence is medium rather than high because the specific cap values could not be independently confirmed from the visible calldata alone.The reasoning has been shortened to remain within the character limit.
