Changes

File Path	Change Summary
cosmos/runtime/txpool/handler.go	Renamed function start to mainLoop in handler type.

🐇✨
In the realm of code, where clarity is king,
A small rabbit hopped, making an IDE sing.
With a twitch of a nose, and a swift little leap,
start became mainLoop, the change not too deep.

But oh, what joy it brings to see,
The code now speaks, more clearly to thee.
For every hop in the digital fen,
Makes the code more friendly, time and again. 🌟📝
