Just In Time liquidity

[kimurayu45z]

Motivation

Like Uniswap V4 Hooks, the method to add liquidity after the order before the settlement is useful to decrease the slippage.

Implementation

By using in-protocol block building like Skip Block SDK, inserting MsgIncreaseLiquidity transaction before MsgSwapExactAmountIn/MsgSwapExactAmountOut, and inserting MsgDecreaseLiquidity transaction after that, is possible.
The right to insert should be determined by the auction.
